'Though it's indeed a Jim Dunlop, it seems to be a "transition" model with Thomas parts.
Received as a present from a guy who received it as a present as well from a Canadian guy that was dismantling a professional recording studio in southern Spain back in '87. Been in a drawer since then.
Sounds fantastic. Very classy. In very good shape.
Now, some more detailed photos of the innards:
Note the DPDT Carling switch for true-bypass added by me
and the external power jack added by a previous owner
