This information original was found on The Unofficial Ampeg Page http: I pulled this information from Google’s cache of the site. It has a note at the top of the page that they were reprinting with permission from the authors of Ampeg: If anyone feels this page should be taken down, please feel free to contact me. Ampegs can be divided into six distinct groups for dating purposes: Each group uses a unique serialization scheme that can be used to assist in dating the amps, but in many cases, it is the features and characteristics of the amps that determine the year of manufacture.

Bobblehead

History[ edit ] During the seventeenth-century, figurines of Buddha and other religious figures called “temple nodders” were produced in Asia. The Beatles bobblehead set, [10] which is a valuable collectible today. What finally prompted their resurgence was cheaper manufacturing processes, and the main bobblehead material switched, this time from ceramic to plastic. It was now possible to make bobbleheads in the very limited numbers necessary for them to be viable collectibles.

Post Cereals in particular packaged 22 million mini-bobble heads of MLB players with its cereal before opening day in The National Bobblehead HOF and Museum held a preview exhibit at RedLine Milwaukee from January 7th, through April 30, , [16] which showcased the largest public display of bobbleheads in history.

Clan Grant Standard. I have a photo in the house somewhere of my father that may be of interest to you. It was taken in the s and shows him with the Clan Grant standard. I was told by my late mother that my father was the standard bearer for the Clan Grant at the International Gathering Of The Clans in Edinburgh (?).

After Contradictions There are numerous contradictions in the timeline, though it should be noted that, in the FAQ section of her website , Rowling has admitted having difficulty with managing mathematics, so perhaps perfect internal consistency is not to be expected. In addition, considering the Harry Potter universe is a fantasy world, it’s possible that certain dates may differ between it and the “real world”.

Despite its problems, this timeline is extensively used by fans and Warner Bros. However, several anachronisms have crept through in the movies, such as featuring the destruction of the Millennium Bridge in the film version of Harry Potter and the Half-Blood Prince , even though the novel and the film are supposed to take place two years before the bridge was built. In Harry Potter and the Order of the Phoenix , the Dursleys are seen to have a flat-screen television, which were not commonly available in the mid s.

In addition the Dursley’s car, shown in the same film, bears a year registration plate. A short film with the movie series cast, The Queen’s Handbag , was produced in as part of the 80th birthday celebrations for Queen Elizabeth II. The skit violates the dating convention by having the characters reference the event, even though for them it should still be the mid s. Problems with time Often when dates are given, they are given with a day of the week that does not match with that date as it in actual history.

This is usually explained as artistic licence on the author’s part. There are also contradictions within the books in this area. For example, in Harry Potter and the Goblet of Fire , both 1 September and 2 September are given as Mondays and, in Harry Potter and the Prisoner of Azkaban, Buckbeak ‘s trial is set on 20 April, but careful parsing of the text reveals that it could have happened no later than February.

However, it was later stated that 22 November was a Tuesday, which it was in

Radiometric Dating and the Geological Time Scale

Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information.

As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.

Marilyn Monroe was an American actress, comedienne, singer, and model. She became one of the world’s most enduring iconic figures and is remembered both for her winsome embodiment of the Hollywood sex symbol and her tragic personal and professional struggles within the film industry.

Clean raisins in a screw-top jar. Put in raisins and water, screw lid tightly and shake. Drain out the water and the raisins are ready for use. Instead, stick a fork in one end and squeeze out the juice required. The lemon will not dry out and can be kept for future use. To cook a cracked egg, wrap the egg in waxed paper, twist the ends and drop in boiling water.

You can quickly shave chocolate for puddings and frostings with your potato peeler. Cranberries add a good flavor to apple sauce when cooked with the apples, and give a brighter color than cinnamon drops. Pastry shells will bake smoothly without blisters if, after placing the crust in the pan and pricking, you place another pie tin of the same size on top of the dough.

No more stirring is necessary throughout the cooking of peach butter or apple butter if you make it in your oven. The oven heat control eliminates the constant tedious stirring and the butter will not burn or stick to the vessel. To poach your eggs without an egg poacher, make a ring of aluminum foil and butter it.

PEACOAT DATING

One guideline to help you guess age can be the country of origin. Here are a few rules of thumb to apply. Before , items imported into the United States were not required to contain a mark showing the country of origin. Many items were marked, of course, but they were “prestige” items – European china for example – where the manufacturer and importer thought the source was a favorable selling point. These “prestige” marks will name the manufacturer as well as the country and are normally very elaborate looking things with lions and crowns and coats of arms and so on – all intended to impress the brash Yankees.

Reasoning that a fuze capable of exploding a warhead near a hot target could also be made to home in on it, McLean sought to put a guidance system entirely onboard a standard 5-inch air-to-ground rocket.

The historical perspective on the development of radiocarbon dating is well outlined in Taylor’s book “Radiocarbon Dating: Libby and his team intially tested the radiocarbon method on samples from prehistoric Egypt. They chose samples whose age could be independently determined. A sample of acacia wood from the tomb of the pharoah Zoser or Djoser; 3rd Dynasty, ca.

The results they obtained indicated this was the case. Other analyses were conducted on samples of known age wood dendrochronologically aged. The tests suggested that the half-life they had measured was accurate, and, quite reasonably, suggested further that atmospheric radiocarbon concentration had remained constant throughout the recent past.

In , Arnold and Libby published their paper “Age determinations by radiocarbon content: Checks with samples of known age” in the journal Science. In this paper they presented the first results of the C14 method, including the “Curve of Knowns” in which radiocarbon dates were compared with the known age historical dates see figure 1. All of the points fitted within statistical range. Within a few years, other laboratories had been built.

I have found the tag size is usually an accurate predictor of how the garment will fit. There are exceptions, however, and I have developed this section to ensure a good fit for a peacoat bought from an online vendor, such as Ebay. A properly fitted peacoat will be trim without being tight. There will be enough room to wear a sweater underneath without binding.

A sweater may be necessary to fill in the space between the body and the inside of the coat for really cold weather wear. It slows the flow of cold air and adds insulation. For example, my chest measures 42 inches. I wear a size 42 peacoat pit to pit of For a trimmer look I can also wear a size 40 peacoat pit to pit of With the fit being closer to the body, however, the size 40 is warmer than the size 42 worn without a sweater. I have found that the earlier the peacoat, the tighter the fit.

The coats after WWII have a little more room in the chest. In fact the WWII models have a trimmer fit overall–chest, sleeves and shoulders–than the post war coats.
