Most guns up to CE-Grade would get a Jostam Anti-Flinch, while XE-Grades and higher normally got a leather-faced Silvers or "Silvers type" pad. We see cards where higher grades were ordered with a Jostam Anti-Flinch. I have found cards that specify a Goodrich pad, a Perkins Recoil pad (which I know nothing about), a #6 Recoil Pad (get from Tryon), D & W Pad, Jostam Air-Cushion, Jostam Sponge Rubber pad (pre WW-I it was the Huntley pad), etc. I haven't seen a Hawkins specified until the Savage years, and very late in the Savage years we see a few Whitelines specified.
