I've got one in a Compur 1 shutter. They probably offered it in Compur, Prontor Professional, and Copal shutters. You should probably send it to Grimes for mounting to be sure the cell spacing is correct. It may have had spacers for different shutters.

Nice lens, by the way, but my Tech V is about an inch too short to use it as a 370mm lens (grrrr...) without getting an extension lensboard or back.
