I saw a 1917 enfield action converted to 375 H&H. Rifle has a full length stock, but no open sights. In my un-expert opinion, entire rifle condition is probably 85-90%. What would you guys say a fair value for the rifle is?

it all depends.. if its just a rebarreled and stocked but otherwise military. not much .. if its a well done conversion, that FEEDS and shoots, 1200?
