The J. B. Peters Air Pistol

[ashf9999]

Very nice pistol and great to see it's been brought back to life. Minor thought re shot size, if they meant #6 as in shotgun pellet, remember UK, US and continental shot sizes vary for a given number, so it could, as you say, be undersized.

Thanks.
Yes, the recommendation was for 0.110" chilled lead shot, which is #6 shot in US size.
I did discover however, that the shot size varies considerably, so it was necessary to keep a clearing rod handy to remove any shot that was far too tight to be fired.

I find it strange that this inventor went to all the trouble of designing, patenting and building what is quite an attractive air pistol and yet was content to have the cocking lever/piston travel such a short distance and so, along with the small diameter power plant, generate so little power. Surely it wouldn't have been that difficult to have the lever bypass a narrower trigger guard and a larger compression chamber travel a bit further. Maybe another prototype with these kind of tweaks exists somewhere.

Might make for an interesting project during the cold winter months here in Canada.
Perhaps scaled up enough to utilize light weight .177 pellets.

Quite an amazing find, Len. Your gun resembles the patent drawings so closely, with a pretty clever design principle even if underpowered. The patent shows a mighty large dead space ahead of the piston leading to the transfer port, which can't help the output. Is the real pistol built that way?

Hi Don,
There are a few very subtle differences between the patent drawings and the actual gun, but yes, that large dead space is there.

Hi Len, hope you are keeping well.
Even though it's not really my scene, another amazing little known air pistol comes to light, nice one Len.
