Trying to source odd cable

I have been lucky enough to acquire (ebay) an ANALOY portable aluminium
alloy identifier in non-working condition and traced one of its faults to a
broken core in an umbilical cable - shortened cable and got it working -
hooray ! However I'd like to replace the cable so it is back to original
length, but it is a very odd composition of cores:
Overall diameter 10mm
15 thin data cores each 0.9mm diam over insulation comprising 18 strands of
0.07mm copper
9 thick power cores each 1.7mm over insulation comprising 41 strands of
0.15mm copper
Two of the thick cores are individually screened and then laid with the
other 7 thick ones
As the rest of the instrument bears all the hallmarks of the Radiospares
catalogue of 1989 when it was made and I suspect that they were made in
relatively small quantities its hard to imagine it was a specially made
cable - though maybe it was.
All I need is about 1.5 meters of the stuff - anyone suggest what it may
have been made for or have an odd length laying about?
Alternatively any other similar multiway cable with those cores in a 10mm or
less form factor (needs to go in the shell of a 25 way D type plug)

In my opinion the cable you described must have been specially made for some sort of instrumentation purpose and I am not aware of anything similar.
My suggestion would be to make up the cable yourself. I have made various leads and special cables using combinations of individual wires, coax cables, pneumatic tubes, some incorporated a kevlar cord to support the weight of the equipment. For the outer sheath you can use Silicone, PVC or braided Nylon sleeving. I have also dismantled screened multicore cable just for the copper braid to create a custom screened multicore.
