On the other hand, the lack of them could simply be, as with the lack of any voltage indication, that it was simply expected to be run from a supplied PSU - so knowledge of what flowed between them was not considered necessary.

By the way, if the above-mentioned PSU is found, measurement and publication of its output would be useful before it's rehomed.
