I've found a lot of similar typefaces, but no exact match so far.

Can't find a match but really doubting there could be one. Feels "customized" to me. Reminds me of Isonorm.
More clients for customization: Millar, AF Module, Greyscale Basic (possibly the closest, only needing /b to be reconstructed from /o + ascender and tweaking /a), http://BetaSans, Neutraliser Alternate

I agree with Ryuk that this is custom. The C appears to not be a useful cap in a whole font - scale is wrong as is placement - this is a logo, not a font.

Thanks folks. Your feedback supports a feeling of my own about this being a 'custom' one.
I think the search is over.
