Original Shansei were made 1928 - 1931 ?? I have never owned one of those, too expensive. The original one might work better. If you're interested in an original one, there is one for sale in the coming March 2012 Julia Auction. I believe this one being an original. If its new owner could give it a range test and post results, I will be very interested.

(This gun, along with another one, were sold in 2008 from the same auction house. On sale again now).
What I owned was a parts gun imported in 1980s. Let alone shooting it, putting it back after disassembling was not easy. Much cheaper though. For looking, it's not bad, but it does not fit my collection well, so I sold it.
