Look what I have - and its raining for a week

G'day all,
I just received my new scope. It's a 12.5" F16 DK Cassagrain (thanks Mark to
educate me) from the 70's AO.
Well its raining so I could not tested but is sooo coool
especially the rotary eyepiece holder.

However I just could not understand the drive and clutch mechanism.
Is there any one who has this eq mount?
Eventually I like to modify it, perhaps adopting it to
a Sky scan kit
I have to get rid of the tangent arm DEC first.
It is not a true tangent arm, very rough and only
a couple of degrees.
The RA drive is a ac motor drive a brass worm true a right angle sprocket,
but the manual slo mo is again the same ex-centric wheel like the DEC axis.
I could not disassemble the clutch. If any one tackle that before could
you educate me please how to
Thanks,
Mick.
