[LargeFormat] Old LF info requested

[Jim Hemenway]

Hi All:

I bought an odd lot of old wooden LF parts which appear to have been
Korona/Graphic stuff.  I'm wondering if anyone can tell me what the
following items are/do?

15x18 inches, the circular part rotates when the thumb screw is turned. 
There is a thin gear all around the circular part.

9.5 x 7 inches.  Felt on the bottom. Marked "Crown Compact Stand". What
tripod would it have been used with?

Thanks in advance,
