Schneider-Kreuznach-Xenar 1:4.7/135 lens

I recently received a Crown Graphic fitted with a Schneider-Kreuznach-Xenar 1:4.7/135 lens and a Synchro-Compur-P shutter. In X what shutter speeds are syncronized for a modern electronic flash such as an E.O.M. like Sun Pak Pro? Does the lens only sync at 1/50?

Thanks.

Synchronising speeds are only an issue when using a focal-plane shutter. With leaf shutters, all speeds are synchronised.

DJ: Ole is correct, the shutter should synch at all shutter speeds, one of the nice things about a leaf shutter. I'd check it before using it on "X" synch for something important. You can point a flash into the lens and make sure it freezes the blade wide open, or take off the graflok back and fire the flash forward and make sure you can see the flash through the lens. Just to be sure.
