I have a 1906 Remington Autoloader (Pre-Model 11),but it's the same John Browning-Browning A5 shotgun. It was in pretty bad shape when I bought it,all of the metal was pitted pretty bad. I disassembled it,and bead blasted everything,and then we decided to parkerize it.
It had the original stock and forearm still,and all the serial #'s match the receiver. I stripped and refinished the original wood,but it turn out so nice,I decided to fit a set of composite A5 stock and forearm to it to preserve the wood set,and keep them from getting cracked from shooting it.
I love this ole shotgun,but being an inertia recoil shotgun,it will get your attention after a few shots. It's the 3rd gun from the left in the picture.
