John, you may be correct as the gun was in Japan at least as late as 1980. The seller told me it was brought to the U.S. from there. Also, one of the stickers on the stock is in Japanese and has a 1979 - 1980 date.

I am aware that Japan was making Greener and Westley Richards copies in the 1930's.

I was hoping that the birmingham proof mark would mean it was an english made gun.

I would be interested in hearing everyone's opinion on what they think it is and its value if it turns out to be a Westley Richards copy.

Thanks,
T
