Hello Martin,

Maybe there is some additional information to give some more clues on the two model plates, one of those does look rather extensive. If there's a letter in front of the serial number, this will in most cases indicate the place of manufacture.

I'm guessing this is an electronically controlled saturated core transformer.

The year of manufacture can probably be determined from the printings on the various transformers, as can the origin (at least of the transformers).

In later years, stabilisers like this were made in the factory in Wavre, Belgium. I'm not sure whether there were comparable models.
