camerastrap for Bronica EC

These are quite specific for Bronica EC. On Ebay nothing until now. Could I use the straps for Hasselblad. They are sold for 30 euro.

You might ask on the Bronica list at Yahoo!Groups. I think there may be a RB67 strap that fits, or something of that nature. There was also a guy named Sam Sherman who had a bunch of new-old-stock Bronica straps for the S2a and EC. I bought two from him, but I don't know if he has any more.
