You're correct. It's the dot pitch of the tube.

Model 1431MS is the standard (0.64dp) version. This is the one that sold
in its thousands. Model 1451MS (0.43dp IIRC) is the high-res version.

There was a (rare) 1441 as well I think. Presumably 0.mumble dp.

The M in the model number = metal case.  Can't recall what the S meant;
I have a feeling it means Standard, but standard what I don't know.
(maybe standard scan = 15kHz)

You can tell the difference between the standard and high-res tubes by
looking at the phosphor colour of the tube with the monitor powered off.
On the standard monitors it's quite a light grey, on the high-res ones
it's a darker grey or greeny-grey.  With the two models side-by-side,
the difference is immediately obvious.  The picture on the high-res
models in modes 0 and 3 is much, much better (text is more readable.)
