Geometric Sans found on mid-60's British amplifier

Font-A-Saurus

It's similar to Johnston, but some details are way off. Check out the "S" and the flat topped "4".

Anyone know this one?

I can't find an exact match (especially one having a short /J) but you may like one of the following alternatives:
Underground by Nick Curtis [1999]
Gill Sans Demi Bold
Chantilly by URW & SoftMaker [1992]

Thanks!
There is quite a number of similar types, indeed. Yet Johnson seems to be the closest match so far.

I'd really like to find that exact font.
