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.
