Nope, it's typical eBay BS. Earlier TR6 used the 1120 (or other numbers),
later ones all used the 1000 (with the gears in the gearbox/OD changed to
accommodate different drive ratios and whatnot).

It's possible your new OD doesn't have the same speedo gears as a stock TR6.
Perhaps it's a unit from a later PI TR6, or one of the other cars that use
the same (almost) OD but different speedometers.
As Mark already pointed out, going from a 1120 calibration to a 1000 will
only increase the speedo reading by about 12% at any particular speed. This
is a lot less than the difference between 30 kph and 50 kph, so something
else is wrong.
