My father has a flash bracket mount for his camera (a Kowa model E
that doesn't have a hot shoe).  It had a long slot with a captive
1/4-20 bolt (with a 1/4-20 socket in the knob) so that you could
position the flash on either side of the camera.  Perhaps something
like that would do as a makeshift slide bar.
