I posted this question on the Bottles Forum but wanted to see you any of you guys have any input. While hunting a site with my 3030, I noticed broken shards of brick. I dug around and I found the base of an old bottle with M.C.Co with the lower case o being higher and a line under it. I found it around where a confederate post was located in Texas. I believe it to be a bitters bottle and hope someone can verify the manufacturer existing during the civil war era. I appreciate any help you can supply. Thanks, JodyReb...
