four digits , is four digits, the value is in the main "frame" any and all the 'parts' can be swapped out to make it "right",,,seen LOTS of 'modified stuff over the years, and just "scrap" them out.....you want a "shooter' that seems fair ENOUGH AS LONG AS IT "WORKS"...........I'd "push" the defects, complain enough and try for a lower price,doesn't hurt to "try",they can only say "no".........'as for thge "four digits" low enough under around 2000 then its a type one, and as I noted above ,its all about the "parts" that are on it anyway...."out the door" at that price or less, I'd be tempted..............but easy to say, as I have all the "parts" anyway, so that is NO extra cost to me 8)
