The snow blower is a 1974 model, made by American Lincoln. It is what is called a 3 stage snow blower (2 augers & 1 impeller). It never was a rototiller, but with the removal of 2 bolts, you could pop the blower off and install a mower deck. I have never seen the mower deck set-up. It was tagged as a Sno-Mow. It must be a pretty rare bird, as I have only been able to find 2 others on the entire internet.
There may be a connection to the Lombard chainsaw company, which would have been well known in your neck of the woods. American Lincoln bought out all, or part of Lombard around 1968. They continued to sell many Lombard products, under the American Lincoln name. However, I have never been able to prove in writing, that Lombard ever produced any snow blowers at all.
I have 7 snow blowers (no known cure). I picked up another 3 stage blower (1964) about 6 weeks ago. I will start restoration on this one in the spring. ---
To keep this more workshop related, here is a pic of my Mill/Drill. I have also restored some shop machines and made modifications. I will get to some photos and details on those as time goes by. --- John
