At the time, at least in the UK, it was a very common extrusion, often 
used for power supplies etc., and in fact I see two on the back of big 
Astron supplies under my bench.  I had some in my "junk box" that even 
had the mounting holes in the correct places.   If anyone needs it I can 
take photographs of the back of my 9475 with the heatsink fitted.
