condition and box ,is about everything, that seems way high to me for the gun alone...heck, I'd put the flatgate back in the gun I have here ( 32,xxx serial number range, type 3... has a premiere loading ) gate, and throw in a pair of nice stags and pay for the shipping to you........tell you what ,you can have BOTH gates at that kind of money.............
need MORE info as to just what gun you may be referring to...........boxed, 3 digit gun, that would be "cheap"..........
