.No i can not post a pic.
no its not 1800s, its 1919 or newer, I know that because its patented 1919.
I only want to know the last year waterbury used the backmark, W.B.CO.
Can you post a pic by a coin? Could be a coat button from 1850 to 1880
i think it would be 1919 to 1949 (posted by Bryan)
OK great work. Thanks. Patents were only good for 17 years so based on the patent, the button dateline would be 1919-1936.The organization was founded in 1919 by veterans returning from Europe after World War I. wiki.
heres a button
I think if the patent is renewed, a new date would be stamped. Here it is renewed in 1935 on a rare Great Seal button backmark turtlefoot gave me for my collection. http://www.treasurenet.com/forums/w...utton-wrong-backmark-war-effort-marriage.htmlThanks everyone for the help.
Yes it was an American legion button That got me wondering when Waterbury last used W.B. CO. back marks and I could not find any more information than what TheCannonballGuy posted about the company changing to Waterbury companies inc. so I thought the last year must have been about 43-44.
Bigcypresshunter , could they renew those patents? Or if they renew it will the patent date change on the new buttons?
It shows a couple American legion buttons here about half way down the page One with the W.B.CO. mark but doesnt list the W.B.CO mark in their list of backmarks?
Patents from the USA
Thanks Pete. Ill have to update my Great Seal backmark thread datelines with this Waterbury company information.For BCH, and any other readers who are interested:
According to the "History" section at the Waterbury Button Company website, that company changed its name to Waterbury Companies (note that it is plural) during World War Two. Thus, the longtime "Co." abbreviation in the backmark became Co's.
I did some additional research to find the exact year, which IF I'm recalling correctly turned out to be 1943. Unfortunately I don't remember where I found that info, so to be sure about the 1943 date you'll need to doublecheck my foggy memory of it. I do feel certain that if you went with 1944 you'd be within one year of the correct date of the name-change to "Companies" and the emergence of the Co's backmark.
Edit: Here are a photos showing two variations of the Waterbury "Companies" backmark. One has "Companies" spelled out, and the other has the abbreviation Co's. Note the "INC" for Incorporated. Also, I've seen a third variation, which says simply Waterbury Co's Conn" (without the "Inc.").
