Ah, ok, so they have their own focusing mechanisms. Can't quite picture those. I bet, at least, with a bit of machining, you could probably attach a mounting flange to whatever old PK adapter seems handy... Is there a retaining ring in there, (if so, any idea what size?) originally, or are they otherwise attached?
Nope, no Lensbaby, though. But, one can always improvise, that's where they came from.
