I had a similar unit on a special back in the 1990's. I seem to think that it was supplied by Nick Plevan who was active in the SA7C at the time, but i may be wrong. IIRC when you took the cover off the aluminium box it was full of resin to hide the electronics within. I recall that I nearly cooked a dynamo whilst using it.
