Mello--
This brought back some great memories. I grew up in Central Cali. Remember a lot of time spent as a kid wandering through the fields around my grandparents' ranch near Riverdale with my Crosman 140. I still have that gun, but it won't hold air any longer. It's been sitting neglected in a closet for years. I loaned it to a relative for pest control and got it back looking kind of beat up. Found your thread on Google when looking for Crosman 140 info. I have nothing but the gun itself, no manual or anything.
Do you have contact info or a website for AB Airgun? I'd sure like to fix mine up and be able to shoot it again. As far as I can tell without tearing it down, most of the issues are cosmetic; it's got some nicks and dings on the stock, esp near the butt, and the barrel and reservoir have some light rust and the finish is worn in spots, especially around the breech.
Cheers,
Jeff
