Apparently I dated myself with Monkey Wards.
Miriam it does have the orange ends and the built-in cams. I don't think I've seen that shade of orange on anything since about 1972.
I haven't taken the top apart yet, it has some trouble shifting between stitches. I'm hoping some oil in there will help. I've got it sewing. I had a few minor tension issues to sort out but it's doing fine now. A little more work to free up the knob that works the feed dogs and a little work on the top to get the stitch selector working and I think I'll have a pretty good machine. I'll also give it a good cleaning. The insides are looking good, no rust and no dried oil residue either. It's obvious it was never over-oiled, possibly not oiled at all by the previous owner, but the outside is pretty grimy, especially the case.
It's keeping me out of trouble anyway,
Rodney
