This suffix letter doesn't match the examples in our technical information section...
It is from a piece being auctioned currently on Gunbroker (search for "rare" and you will find it.) The suffix letter on the lower frame under the barrel is identical...
Anyone care to comment on the seller's story about this suffix letter or perhaps have a good reference for this suffix example??
regards,
John Sabato
