The Mauser Type A (if that is what you are referring to) has a small sized 'butt' and Pachmayr make a small red Old English Decelerator pad that will look good on the Type A. My Type A 404 came from Rhodesia with a brown ventilated pad, white line spacer and all, which I replaced with the said Pachmayr pad. Soaks up the recoil far better than the ventilated pad ever did.

Before - white line spacer removed

After - Pachmayr Old English Decelerator
