My late pre war 21 came with the red Winchester pad from the factory. The gun had enough features that didn't add up but appeared to be factory work to pique my interest enough to get a letter. Some of the things that raised flags were that it's set up like a Duck model but with 28 inch barrels. The letter showed that everything on the gun was actually as ordered. My best guess is that the original purchaser wanted a Duck but not with the longer barrels so Winchester built the gun that way. I'll say that the stock on it is VERY comfortable due to how the comb is proportioned thickness wise.
