Had my Rolleiflex 3.5F apart recently...and could not get its Compur shutter to work on all speeds.

Usually I'm pretty good at DIY-ing this sort of thing, but in this case I'd rather just send the shutter (which I'd remove from the camera first and send "naked") to someone more competent than myself.

At any rate...if anyone could let me know of any competent repair folks who could tackle my Compur shutter - that would be great!
