Quick focus handle for Hassy 903SWC?

[Trask]

I have a quick focus handle on my older chrome-lens SWC, but I see that the 903SWC has a different focusing ring -- anyone know if a quick focus handle is made for the 903SWC? I find that they can be very helpful.

Think there were two OEM ones for different diameter lenses google for instruction manuals
