Looks to be a Poulan 2300. I don't have one but others here seem to like them. If I'm correct it superseded the venerable S25CVA, which I feel is an outstanding saw. I'm sure someone will chime in.

The 2300CVA was out in the early 80's and it never did or was intented to supercede the S25 series. In fact the 25's were made into Poulan Pros and were produced way into the 90's
I have a couple of the 2.3 Poulans but haven't used them enough to tell how good they are, but you sure are correct on the 25s.
See above.
