Tom:
Given the origins of the bike, my vote would go to GB centerpulls, such as the 66, which are quite aesthetically pleasing. Nowhere near as common as DiaCompe/Weinmann/etc., but they're out there and not hideously expensive if you look around. Personally, I think either Mafac or Universal would not be appropriate for a Hetchins. Hilary Stone, Martin Coopland, Pete Paine, and others are good resources for some of the British bits which didn't make it to this side of the pond in large numbers.
Hope this helps.
