Hi Gribnitz
Congrats on your nice finds. I always enjoy looking at what other TH'ers are findng and appreciate good pictures especially when additional details are provided as to what the items are (if the auther knows). I just purchased the book 'Civil War Artifacts A Guide for the Hisrorian' by Howard R. Crouch. If there was ever a book that will make you drool this is the book that will do it. I was trying to find the rivet looking item in this book but was not able to find it. I will do a more in depth search as I have just found one yesterday that is very similar looking.
Congrats again.:-) I have attached a picture of my best find ever. It took me 26 years to find this one, but I am still looking for additional ones to go with it. Good Luck in all you do, have fun, enjoy, and stay safe.
