[Milsurplus] APS-20 & APS-31 Radar Info wanted please

[Dave]

G'day all,

APS-20 (or A or B variants)
APS-31

A friend of mine here in Australia has most, if not all, the components 
of both of these radar systems. He also has most of the cabling. 
However, we are in need of Interconnection diagrams for both of these 
systems, if possible, so that all the component units can be connected 
together for static display purposes.

If anyone has access to these diagrams and can scan, we would be very 
grateful. Obviously, if a pdf of either/both these manuals is available, 
we would like to hear about it, please.

Cheers
Dave
