I bought a Grant one time that had been re-stocked with a nice piece of lumber. I knew it up front going in. The problem was the forearm was original and the wood did not match. After awhile of looking at the gun in the safe and seeing the difference daily I dumped the gun.
Did it fit? Yes Was it a nice job? Yes Did it bother me? Yes
Oh by the way there is a Holland Royal on Gunbroker right now that has been re-stocked, looks nice but you can tell definatly it is not original to the gun and probabley not by Holland.
Take a look fisrt hand and let's hear what you think.
