I would like to call members attention to a rifle listed on GunAuction (not GunBroker); their #16958616. The rifle's serial number is 3357655. Like the 03A3, it has the flat tang and the absence of the contoured milling cuts on the cut-off boss. I have one, #3285588, with the flat tang but mine has the contour cuts on the rear of the boss but not the front. What I find different about the GunAuction rifle is the flats front and rear on the bridge. I haven't noticed that on other 1903's. Any comments?
