Another customised patch lead from days-of-old in the workshops, I think this was used for a wired remote controller of some VTR gear or perhaps musical equipment in the days before IR remotes (Yes, a long long time ago!)
Although multi-pin connectors at each end of the lead, in fact this is just a two core shielded cable.
