jfreakofkorn. Be sure to have it authenticated first. I'm not trying to to be a smart ass here,, but,,, there were some very very well done replicas done just a few years after WW11 that were 100% correctly marked and looked out rightly to be the real Mc Coy,,, but weren't.
Want to ask me how I know???? I got burned by one. And only found out after bringing it to the Antiques Road Show for an insurance appraisal after it had been confirmed as an original by a high end local antiques dealer.
Be very careful with those type things, even the copies have a good patina at this point, so that's not necessarily a good indicator of age. Just a heads up,, honestly ,,I'm not trying to cut down you treasure. Mine sure wasn't what I thought it was either and I don't want you to find out the hard way like I did. And making enemy's in the process by trying to sell a fake, inadvertently or not.
Just some sage advice on those. Unless you know 100% the provenance, don't assume like I did. Get an authentication first. Anybody can say anything about a war relic, true or not, don't take chances. I fucked up on mine not getting it authenticated by a blade expert ,, and it cost me,,,,,,in money and customer confidence too.
