Simple. They never made a 1800 model. They did make a 1088 model and a 1861 model. This question bothered me so I kept searching for an answer. I found Crosman made a model 1600 powermatic from 1979-90 it was a BB pistol. Check you numbers again I think your "8' is really a "6". If so, then it's a model 1600 powermatic.
Yes but it is best to make it a head shot, or the squirrel will suffer and die.
The Crosman Bullseye Target model 105 is a pump pistol made between 1947-52
