Shutter for large format lens

[billthecat]

I have a 4x5 Speed Graphic and I'm adding old Petzval lenses to it. The built in traveling slit shutter works fairly well for sunlight, but I can't use flash with it. My lenses are about 2 inches in the rear. Does anyone know a place to buy a shutter for a 2 inch rear lens element? I checked around but couldn't find anything.

Thanks,
Bill

I have a couple of Shanel 5A shutters, which are used for mounting barrel lenses. The shutter has X and M sync, and speeds from 1 s to 1/100s. The opening is ~64mm dia, so you're good to go, so long as you get an adapter ring to fit your lens. You'll also need a retaining ring to hold the shutter in place on the lensboard. PM me for more information.
