Maybe the B.J.W. & Co. is some American Import house or the like:
B.J.W. & Co., Lock Box 46, Mercer Pa.(Pennsylvania)????
For the moment with the information @ hand, me thinks it was made in Liege in the white & shipped directly to the Birmingham proofhouse where a maker their entered it as their own wares & then it was forwarded on to a client/importer in the U.S. of A. & peddled here? It is possible some effort was applied in Birmingham before its arrival in the U.S. of A. There was an exception in the Belgium law where it could be shipped naked of proofmarks to another acknowledged proof facility. In Birmingham, if it wore any foreign marks(typically Liege) it could be declared "Foreign Make".
Any history with the piece? Any other stamps on the action or locks?
Cheers,
