Well... there was presumably a change in the internal keyboard layout to
accommodate a 102 (rather than US 101) key design. If that fab was done by IBM
outside of the US then it seems entirely possible that they retained important
bits (s/n, p/n and "IBM" text) but that the "Model M" name became lost
somewhere.
(I believe that the 102-key layout was sufficiently generic for most non-US
markets, so it wouldn't surprise me if other non-US Model M's lack the
branding too)
I can't think of a reason why "Model M" would either have been frowned upon
in
the UK or infringed on some other keyboard-related territory that involved the
name. I suspect it's pure fate (and not even a screw-up).
