Howdy Everybody, I found this little item in a small community near a turn of the 20th century mining area ( 1890- 1920 ) in Arizona. I have posted on other sites with no luck of knowing for sure it's ID. There has been some great speculation and I appreciate all of that , however, it's still just speculation. Lantern hook, boot pull-on, bent ring, corn sheller and my favorite is corset tightener. Please don't stop the spec. but if anybody knows for sure i would love hearing from you. The outer curve says " Pat Jun 14, I think I can see an 8 after 14" and I can't make out the year, on the inside curve it says "Pat Jun 8" and I can't make out the rest. I tried to do a patent search searching June 14 Of all the 1880's, but for some reason I can't get any description or drawings to come up from the Patent office. The material from which it's made is hardened copper. Thanks for checking my post.
