Model 49 snowblower that I fixed up from very poor shape, had some rust but no rust through anywhere, I just put a tall chute on it (I haven't even used it since), and it could have a spout control put on it. The spout is lined with fiberglass and has no rust in it. The spout control handle is removeable for easy transport/storage. I put new gears in the 90 degree gearbox in 2018 IIRC.

Here is the rebuild thread on this snowblower:
