Twin SU carburettors

That little aluminium tag attached under the screw on the float bowl has a number stamped on it. This says what car they were manufactured for.

There should be one on each carby - I can see one in the picture on the LH carby.

The top dashpot damper number means little these fit heaps of SU's.

The tag reads AUD533F is there a web site I can punch this number in to find out what car they belong to?

I think I have found a site, seems they are from a 1971-1979 2000 TC P6. the AUD 533F is the front and there is a AUD533R at the rear. here is the site if you are interested

Thanks Rob for your help

They look to me like pretty large ones - at least 1 3/4", so off a large four cylinder if that narrows it down. Too new for a Triumph, though.

According to the Haynes manual this spec was used on a 1971-73 Rover

2000 TC (not USA). The suffixes F and R refer to front and rear carbs on twin installations (Rolls-Royce used A and B). Transverse engines and V8s have L and R for left and right. There is also a C suffix for the centre carb on triple SU installations.
