[TowerTalk] CDR/Hygain Rotators Shameless Questions

[Wilson Lamb]

I have a pile of rotators and parts from an estate.
Liquidation is already taking an absurd amount of time, SO
can anyone point to the best source(s) of documentation?
I have a manual from the web.  Pretty good, but there is no exploded dwg of the rotator unit.
I have a CDR HAM 115V controller. 


 CAN it control the later rotatore, like HAM 4?


What's the best source of parts, should I want to try to reassemble one?


Is there any value in disassembled units?


IF you can save me some search time I'd surely appreciate it!


Thanks,
Wilson
