I have a ’57, and found a parts listing online, probably for a ’58. Also found a West Bend service manual that generally applies. I can try to find the links if you need them, or email them to you.
The model number looks to be 574.601??, I believe this makes it a Scott-McCulloch ??, not real familar with these, just picked it up as a change of pace.
Mumbles, the link you gave seems to cover it pretty good
That would be the one. Cosmetically it is pretty good, haven’t really had a chance to check it over yet to know what kind of shape it is in. One of those deals where I don’t really know why I picked it up, was just something different I guess.
