Hello, all you dust devils! My late father owned a 1950's-era
Shopsmith and my mother is thinking of selling it. I have asked her
if she can find the manual, but in the meantime I can give you the
faceplate info. It's a Model ER, Serial No. R67986, Patent Applied
For.

I have seen Shopsmiths for sale referred to as Mark II, Mark V, etc.
Anyone know which this is?

Thanks,
Jeannie
