Hello everyone! I purchased a shotgun at auction and have no clue about it. Bought it since I saw others sell for a nice amount in the USA and Europe. I cannot find any info about it. Looking at it, has a few stamps and serial numbers but no date code or anything. Says S.Berry EDMONTON on both barrels and that is all. Has some rust and I do not know if I should keep it as is or try to freshen it up? On the gun it does say M Ugarteburu Model Uplander
