I just picked up a cheap condenser and AN slip-on glass from a Focomat, and they are NOT compatible with the original Valoy. Not a big deal. More interestingly, I picked up what looks to be a 1B on ebay for $60 shipped. Anyone know anything about this one? Almost no information about this model online anywhere that I can find.
I know that it was less sturdily made than the 1c.
