Ok, here's the scoop. I just called Erskine Mfg (the number given in the links is correct). I spoke to a very helpful gentleman by the name of Rene. Erskine has discontinued the production of this particular line of snowblowers. I have given him the URL for TBN and told him that there are a number of people who may be interested in finding any "left overs". Apparently they made 5', 6', and 7' blowers with a 1' wing that would extend. He was quite interested in the fact that they were a topic of discussion. He indicated that if there was enough interest they could potentially resurrect the line. Their current focus is front mount blowers for tractors and hydraulic front mounts for skidsteers.
Not sure what you guys want to do with that. I would love one, but with the conversion to USD plus the shipping to Alberta, I think I'd lose in the long run!!!
