I have a B&L Rapid Rectilinear (~1913?, ~165mm) adapted for the Bronica by mounting the Ball bearing shutter in a Bronica body cap and then using the extension tubes to give me the approrpriate length... similar to the assembly that David described. It actually turns out to be one of my favorite lenses. It is about f/8 and I have a Series VI adapter I use on it with an ND filter or yellow Y1 or Y15 to keep the exposure in the range that I can shoot it wide open. I can remove the ball bearing shutter and mount another of my 4x5 lenses & shutters in it, but the RR is the best.
