<p>Jon, <br>
Don't know if you are still pursuing an answer to this, but I purchased an SWC/M from a former Hasselblad rep in NYC that sold cameras to Mr. Friedlander. The kit that I purchased had two Vivitar flash units taped to the squarish lens hood for the CF Biogon, connected into a PC connector star and then into the PC connector. I took it apart since I wasn't using it and wanted a spare lens hood. This might be a solution for you? </p>
