Like Bob, (redunshee) said, its definitely a Poulan. The trick is to determine wich one, 3.4 or 3.7. If you look at a post or two ahead of yours, you will see a pic of a couple real nice 3.7's.
I'm not UP on the Craftsman model numbering system. A pretty sur way to tell is pull the muffler. The 3.4 version will most likely have a chromed piston with unplated cyl. The 3.7 will likely be just the opposite. with a slightly larger exhaust port. Most of those saws had decals on them. 3.4/16 or 3.7/18
Parts are interchangable with all of them, and with the Poulan versions.
Gregg,
Well it definitely does not have a chrome piston and the exhaust port looks pretty good size to me but I'll try to post pics later it has a 20" bar with replaceable nose on it also but I can not find any model number on it any where
