Hello there Max,

I thought you might find the information in the article I found on 'Jimmie Dee's Airguns' website interesting, as it explains a lot about the Challenger Arms Corp Plainsman Pistol pneumatic air gun and the history in the making etc. :

If I am not mistaken, I have found pictures of your gun with the same query on 'Airgun Nation', so I hope that I am on the right track as it looks very similar to the pictures on Jimmie Dees' site, some of which which I have added below ...

Thanks so much for sending information. I have been aware of jimmie's posts and photos for years now, and they are an excellent reference.

... further more and probably more in relation to your pistol markings perhaps and I quote from Jimmie Dee's Airguns website at http://www.jimmiedeesairguns.com/pistols/the-challenger-arms-corporation-plainsman-co₂-pistol-1954-1958

"The CO₂ Plainsman pistol was also available in both .177 and .22 calibres although today, .22 calibres are more commonly found. I have only seen one .177 calibre CO₂ Plainsman which suggests that they may not have been produced in as many numbers as the .22 variant. There also appears to be two sub-variants of the CO₂ Plainsman as some are marked with the calibre on the right hand side of the breech housing and some are not. Also, some that are marked with the calibre are also marked “C” perhaps for CO₂ whereas others are just marked “22” or “177”. It is possible at some stage it was decided not to stamp the frames with the calibre to reduce costs on the production line as the barrels may have been interchangeable."

Happy reading and happy airgunning!

Okey-dokey Max,
you're welcome and that's my pleasure to try and help.
