Hello Graeme,
Your find looks much the same except without the white ring on the edge and possibly not as glossy. Here it gets complicated. Checking my vendor's comment on his advertisement comparing his item to the Moss version, that Moss (US) number is a reproduction for the MGA and AH 100, 3000 models equipped with the washer. That Moss Knob is available separately but there is only a drawing and the pump does not have a separate number as it is part of a kit. Those Moss knobs may be the same/similar to the ones we found. However, given the vendor's comparison (and his is a threaded version), I am guessing that the replica Moss US pumps for MGA and AH are threaded as well (again there only rough drawings).
I have been checking on pumps for my TR3A, since my current one is one of those simple black plastic plunger types. Again, Moss USA only provides one as part of a kit (and they specify it for TR4/4A only), but they sent me some pictures and it looks exactly like the one Moss (UK/Europe) sells as a separate and they are threaded for the knobs. The knob provided in the US kit is clearly for the TR4. I sent questions to Moss UK and should hear from them tomorrow. While they list it with a photo as being for the TR4/4A, it is also specified for TR2/3 in the catalog lines. My guess is that the front bezel part that makes it conform to the TR4 dash is removable - and Moss US suggests that it might be - by removing two retaining nuts. It is also very possible that they are using the same pumps for the TRs and the MG/AH solutions but with different bezels. Here are some photos.
Moss USA and Moss UK market their parts differently; sometimes as separates, sometimes as packages - and of course they have different numbering systems, with Moss UK adhering to the original TR factory numbers - but they are rarely different parts in my limited experience. Mind you, it is only deduction but given all of this, I think the knob from my vendor (and likely the part from your source) will fit on one of the Moss replica (not replacement) pumps; possibly also on an original pump with threaded fitting. If not, I would make mine fit.
And here is the kicker. While poking around on Moss UK pages to compare the MGA/AH parts, I found that they sell the pump and knob as an assembly. The knob looks like the version you found:

So much for my obsessive-compulsive investigations....will let know what Moss UK tells me.
