I just picked up an rusty Remington Rolling Block rifle at a garage sale. It was actually made into a lamp. I freed the rifle from its terrible fate. I have cleaned and cleaned and actually got the the hammer,trigger and block in good working order. The rifling looks great. The wood stock has the # 534 stamped on it and what appears to be someones intials carved in the other side of the stock. After putting calipers on the barrel I believe it to be .430 caliber. From what I can find on the net these were exported by Remington. PLease enlighten me with any information you may have on theis rifle. It feels great against my shoulder. Very east to hold your aim.
