Winchester offered more than 20 recoil pads ( special order) and the Pachmayr white line was available in either a 1 1/8" or 1 3/16" version for $2.50 extra
This is where the lineage and collection of pre 64's gets really muddy. With the amount of recoil pads offered, and all of them were also offered as aftermarket additions by say a gunsmith down the street. With the premium paid for " special order" pre 64's it is very easy to say it was a special order. Now having the proof ( original box, build sheet, letter from Winchester, original tags) is another story. Could this rifle in this thread be original??? Maybe... Maybe not. My opinion is it isn't without proof. I have been collecting pre 64's for almost 20 years now and have a couple rare ones. Every once in a while you hear the old story of " my brothers best friends uncle has a friend down the street with a rare special order pre 64.... but doesn't have any proof"... In my eyes than it doesn't have proof at all.
google box " selling dads old guns".. read the winchester collectors blurbs. That guy took a bunch of pre 64s and fabricated boxes, tags, Cody letters, etc... One guy even called him out because he recognized the serial number of a rifle that he had sold that was NOT new in box and used well and now this guy had it in pristine condition and new in box with tags and a Cody letter.
