Generator/Motor Identity

We collected a smallish DC machine today, on the way back from one of our
customers at Aylesbury.

There is a nameplate, but nearly all the etched/anodised print has gone, leaving
only serial numbers which are stamped.

Pictures are at:

Any ideas would be appreciated.

The commutator diameter and number of segments suggests 24V, there are two pairs
of brushes and what looks like a conventional shunt field, one terminal of which
comes out to the 3-pin socket on the side, along with the brush connections.

It might be a motor, but I feel that it is a generator.

The coupling has an almost snail cam form inside, possibly to take a rubber
insert to transmit the drive. There is a carbon contact on the non-drive end
shaft, presumably for earthing.

Pictures are full-strength, taken with 1.2mp camera. Small cheese-head screws
are 2BA (vent covers etc) Body etc is all cast-iron.
