Nylon, Plastic, or Metal Camstack?
 

Good question. I take it you're not able to open it and look?

Get a screwdriver. ;)

My money wold bet on nylon.

Take the top off and look. If a magnet sticks to the cam stack they're steel. If not, they're not.

Wish I could get a screw driver and take a look. It is being sold on CL and is a bit of a drive just for a look. The seller does not understand what I mean about camstack, I guess.

Without actually eyeballing the cams you really can't say for sure. There's a good chance they are plastic. If they are individual cams joined in a stack on a shaft like my Alden,

then they are not as prone to breaking as the solid cam stacks used on other machines. They are sort of like the flat cams Singer used in many of their machines.

Were I interested in the machine you posted about, I'd take the drive, check it out to make sure it sews on all cams then probably take it home.

Good information, thanks.
