Information on C-Clarons? (not G-Clarons!)

Does anyone have information on C-Claron copy lenses? Is this a similiar formula to the classic G-Claron? Comparible coverage?

Regards,
Jeff

The C-Clarons are not for photography, they're for machine reproduction purposes. Although they frequently sell for very little money, having the glass re-mounted in a usable barrel or shutter would be expensive and the result dubious.
