To my eye that pad appears to be the color of the repro Ithaca "bridge trestle" pad made by/for Ithaca when they were at King Ferry, New York.
The Ithaca "bridge trestle" recoil pad that first appeared in the 1931-2 time frame --
had "PAT.APPL'D FOR" across the bottom of the logo on the face --
up through at least 1941.
In 1950, Ithaca introduced their "bridge trestle" pad with the aluminum base.
The Ithaca recoil pads with the black base made at King Ferry New York, have "PATENTED" across the bottom of the logo.
