Yes SU H1 Carb.
Minor carb details from sucarb.co.uk/Burlen Ltd, Salisbury.
AUC452, H1. 1951/52
AUC704, H1. 1953 >
AUC738, H1. 1954/56.
I cannot make out the number cast into the side of the carb reference your picture?
There is usually a tab attached to the carb with the AUC number stamped on it.
There are minor(excuse the pun) differences with the above carbs and it is best if you can quote the number of the attached tab.
Looked again and noticed that the remains of the AUC tab minus the AUC number are under the float chamber top nut.

SU H1 Semi downdraught, ie the carb is at an angle and the float chamber is horizontal. The Series MM also has an SU H1 carb but it is mounted horizontally.
Your piston damper should have a brass cap, not plastic
I bet you'd get one for less than you're paying for that repair kit. I've got 2 carbs which are surplus to requirement- complete with manifolds, off 948 engines. Let me know if you want one, as I'd sell it for not too much.
