SAR .177Japanese air rifle

Shinbishi SAR .177 youth airgun.

Today we examine and shoot it at 25ft. Averaging 451fps.
This is a Japanese .177 imported to the USA in the 1960's. this one has a stamp ending in 61. It was in great shape when I received it but was tore down, cleaned up. The metal has been reblued. I made a leather breach seal and piston seal. the gun was resembled. I left the stock in it original condition. I may refinish it later.
