XK120 Rev-Counter

[Lax Power]

Saw this on the 'bay:

I was wondering if all XK120's had reverse rev-counters and if not, which ones did?

I thought all XK120 & 140 rev counters were anti-clockwise.
The XK150 has a clockwise one. Just guessing, but I would have thought that the Mk9 also would have had a clockwise one. By the time the Mk9 came out, the XK150 had moved to using an electrical tacho so I would have expected the Mk9 to have as well. (No doubt Lowdrag will be along in a mo to correct me )
