Well...yes and no!
Yes, they're Commando instruments, but I believe they are in fact later manufactured replacement parts, and not actual original equipment, which I believe is why they both have the 'A' suffix, possibly because they've got the later green globes instead of the solid green spots, but still have the earlier '68-'70 pattern dials.
I believe the original RSM 3003/10 revcounter was superseded by the RSM3003/12 item for '69-'70, and the RSM 3003/12 still had the solid green spot and not the globe.

I suppose you could say they are a matched pair, but for 1968 (or maybe into '69?). As the SSM 3001/02 speedo appears to have been the correct Commando item from '68-70 as only the revcounter changed to the /12 type, possibly because a red zone was included (anyone know if the earlier units had one)?
But it's only a minor technical detail and not really worth worrying about.

I talked to a guy who rebuilds instruments here in Portland. He sells under the name aprivatepeace503 on ebay. He said that the "A", "B" and other letters designated the production run. No letter being the first 1000 units, "A" being the second 1000 units...
But...
He also thought my 1972 should have the Green Dot, whereas it should have the Green Globe...
Also there is this anomoly:
The gauge on the right is a 3001/02A with a Green Globe. Theoretically it should have the Green Dot. So who the hell knows. :roll:

Think how many Commandos must have had those particular green globe instruments '71-'74, certainly many thousands of them, so where are all the C,D,E,F,G, etc...units?
The letter suffix (usually A) denotes a modified or upgraded instrument, as far as I know.

Yes, he would be wrong then-wouldn't he?

I'd guess it's a replacement unit from a later Smiths production run? That's why it has the globe instead of the dot, but it's meant as a replacement unit for an earlier Commando model, that's why it has the "green dot" style of dial.

One would assume that a replacement gauge for an older bike would look like the original gauge, and have the green dot. But we assume a lot of things with these old bikes. :mrgreen:

It does-except for the logo?
I would guess the Norton factory may have been reluctant to sell replacement parts that still had the old out of date "corporate identity" logo on them, or maybe Smiths were only tooled up to print the green globe logo by the time those "A" units were made?
These are my gauges:
I bought them new in the early nineties when I rebuilt my Fastback. The picture was taken in 2002, but the gauges are in great shape, to my knowledge, they have never seen rain, only the occasional wash. If anyone is interested they are for sale, as a pair with the bezels, cables and the speedo gearbox.
