I had this tool given to me and it actually still works but is in dire need of a new power cord. I’ll check it when that’s done but if it’s a piece of crap it could make an interesting ray gun. The instructions are copr. 1949.
I love weird old tools. Great find!
Can you imagine a dentist using something like that on you?
What is that used for (4)?
Engraving and carving.
I sold one of those at an estate sale a few months ago…astonishingly it was complete as yours is.
