I think I found the answer to my question. I think its a 1953 Model 33 McCulloch. Pretty cool and pretty heavy. I actually went to an estate sale and bought 12, yes 12 vintage chainsaws. Basically I just have been cleaning them up as they have been on the shelf for a lot of years. But a couple of them I was able to drain the old gas and oil, put in new and they took off. I know there are forums for old chainsaws but I thought I would share a picture of my oldest saw here.
