This is not A Pre A Gun, as I am told, Bolt serial# matches gun, later .550 sporter barrel, this is .600, no barrel band. The Unertl bases are the early shorter spacing not the 7.3 . Thats as far as it goes with me. The seller got ahold of two reputable dealers that verified what he had. I am just amazed that there is an 84 year old 22RF that is in that good of condition, a comparable gun sold for $6200.00. Thankyou , I am done and have no more to say on this gun. Appreciate all replies......
