I have 1 I pulled out of the barn about a week ago, think I bought or traded for it at a swap meet last year. Was may be gonna use the sprocket on an 020 but to my surprise it fired right up, sounded good and oiled, so I am looking to put on a bar and chain, test use, then sell it. If every thing works good as expected I expect $90 to $125 depending on bar, chain and sprocket that I outfit it with. Sprocket on it now would work, but if I put on a new chain I have a like new condition 1/4" pitch sprocket I'd want on it. Think I have a nos and a used hardnose both, 1 of which I intend for an 020.
It doesn't look like its been used a lot but it is currently dirty on the outside. I think it will look fairly sharp cleaned up.
Let me know if that interest you and if so will try to get the bar, chain and sprocket on sooner and give it a try. Its sitting on my bench now. It does have a good air filter and I haven't noticed any defective parts.
