I have a vintage 16" Craftsman chainsaw from the 70s that is very well made. This is the 3.7A and it is a beast that has been kept serviced and was built to last. This is a hi-compression saw with a compression release to aid in easier starting. Also has a new bar and chain. If interested you can message or call me on my home phone between 10 a.m. and 10 p.m.
