Hi again. Thanks for the enlargements. To answer your questions, on the water table are the serial number of 016, the original 2 Black powder proofs and the post 1954 Crown over BNP nitro proofs. Nothing else. The forearm lug under the barrels, also shows the serial of 016. "Patent Ejector" is also stamped under the forearm latch, which obviously relates to Baker's trigger and ejector system. Again, thanks for all assistance.
