Mystery engraver

[Road King]

I recently acquired a rifle that was told to me was engraved by a master engraver in Okinawa Japan in late 50s or early 60s,I was wondering if anyone recognizes the engraver. I know it is a long shot. There is a mark on the lever that may give a clue.

This photo shows a mark that may identify the engraver

Thanks for any help

roger bleile may have a clue. if not, try to see if there's some sort of engravers forum in japan. you never know what info may come to light. in my years i've seen 3 war era guns done in japan. yours looks to be a bit better than the ones i got a look at.
