That restock is not that old. Total lack of dings in stock is a hint. I thought there was one area of dings but other views showed it was just heavy ripple in finish. Nothing like thick coats of Truoil type finish slapped on. The inlet around the receiver is over in most areas but short or under the metal in others.
That stock is not going to break. It is a .410, with a through bolt. Recoil wont kill it. The recoil pad will protect the toe area I know. It is just such a dreadful job in layout. And for what reason? That is a common lowest grade blank. $10.00 each. It is not a fancy blank which was laid out this way to show exhibition figure. They should have thrown that one back on the firewood pile and picked another. What it was I suspect was a blank the someone cut out into a near sized shotgun blank and they just used to. You see them on EBay all the time with a $9.99 starting price.
The gun in question is a 1940 gun. Standard rib fore end was not replaced and is not well matched in color. The seller would have been better off buying an original 42 take off stock off EBay for about $50.00. Then it would have been a better match looking like an all original gun.
