Was gifted a Crossman Model 112 22 cal pellet pistol. Looking for a Reasonable Knowledgeable Individual that is familiar with this pistol. The compressed air or CO2 pressure cylinder is marked ICC-3E-1800-TMC8-49 The tank screws onto the front of the pistol. I have a small PCP compressor that I use with a Beeman 25cal rifle. Can possibly adapt this cylinder and fill it with my PCP compressor. Were these cylinders intended for compressed air or CO2 ???IMG_0410.jpeg
