Hi, just signed up for the vintage forum.
I found a very complete 1973 Argo 400 snowmobile in the bushes and have found out there is not much information on the sleds.
Made by Ontario Drive and Gear company in the early to mid 70's makes it pretty cool.
Does anyone have any information, manuals, parts, etc. for these sleds, there must be more out there.
Will get some pictures soon.
