The 3 in my collection that look to have "been there done that" are:
1909 Finnish captured SA marked mosin 91. It's got dents, dings and has been used that's for sure.
1940 Turkish Mauser, again dents, dings, zero bluing and the best part is it has a buldge in the barrel from a bore ubstruction that was shot out!
Last but not least is my 1861 Snider 3 band. I bought the rifle in 2 pieces, the stock was broken in 1/2!! The best part is the buttplate, looks like someone used it regularly as a hammer!!
