Depends on what is meant by "authentic". An truly authentic M91/30 PU WW II sniper just exactly as it was used in WW II and never refurbed would likely be $2K to $3K and up...but it is probably in a Soviet museum or attic somewhere. If by "authentic" you mean a totally genuine Soviet arsenal refurb from the post WW II era, maybe $800. to $1K. I do not use the word "authentic" to describe a resurrected ex-sniper - even if all of the parts are genuine because it never left an "authentic" Soviet arsenal in its present condition. It is cobbled up from original or replica parts. Not necessarily a bad thing, just not "authentic". DDR
