LF Retaining Rings

[Dan Fromm]

Typically $95 plus shipping.

John, your memory is failing again. See http://www.skgrimes.com/flanges/indexm.htm , they quote Copal 1 rings at $10, flanges at $35.

[Ole]

I probably have a spare flange...

FInd the oldest camera shop you can that has not changed hands in a while. Ask them if they have a drawer of this stuff or a box. You might get lucky. Paying even ten dollars for what amounts to a nut at a local hardware store is plain silly in my view.
