For a straight gripped CE-Grade 28-inch 12-gauge in that condition, that aint bad. You may never find a similar or better CE-Grade for less. I sold a reblued 30-inch half-pistol grip CE-Grade with a big epoxied up crack in the head of the refinished stock and with a Pachmyre Olde English pad to one of our big dealers for over half that price many years ago! It was in the 292xx range, shipped May 1924, and had a Fox-Kautzky SST. Oh, it also had a small ring bulge in the left barrel! I shot a lot of Doves at the pond by the old hacienda on Camp Pendleton with that gun in 1972 and 3.

That Hawkins pad may be a bit newer then the gun, but is "period" and looks well fitted in the picture. Even if it is "right" a letter may not mention it.
