Good info. Glad guys like you are here to help. Are the Mosin semin bayonet recently selling for $900 unissued, unrefurbished? They seem to be from the descriptions, plus they are priced at a premium.
Most Semins I saw were reblued and stock covered with extra layer of laquer, at the same time most of them retained original parts and had so signs of service whatsoever. Few had stocks in original condition and other few retained original bluing of metal parts.. Also some had replaced and force matched parts. So "light refurb" is commonly used to describe Semins condition. I think I saw one that I would say was definitely issued or used. That was an exception.
Here's some observations posted about those Semins: https://forums.gunboards.com/showth...0-with-Semin-Bayonet-protoype&highlight=Semin
