Reply To: Crosman model ???? oler gun
It’s a Crosman CG Co2 gun- the tank is for bulk fill Co2. They’re similar to the 101 series guns. There’s lots of knowledgeable folks on this forum-http://www.network54.com/Forum/405945
You have to join to post and that can take a while, D.T. Fletcher from there is really knowledgeable about old Crosman guns and has written a few books on the history and repair of these classic old guns.
Here’s an article on the rifles-https://www.pyramydair.com/blog/2006/11/nothing-new-under-the-suncrosman-cg-series-co2-rifles/
Your example looks to be in very good shape for it’s age, I wouldn’t be surprised if it was still in working condition. There’s probably a way to adapt a paintball Co2 tank to make it easier to shoot-Tim at Mac 1 Airguns in California can probably set you up with what you need.
Good luck and keep us posted, those are cool old guns!
