....and what was the outcome?

Seems it's a PowerSpark distributor.

Hi, still trying to find out what I have got. Can anyone tell me what/who's electronic distributor this is (photos below)

Thanks everyone for the info.

I have just bought a 13/60 and I am trying to understand as much as I can about it. I am perplexed with the engine number which is RD1226ESS. I have looked it up and RD is supposed to be a FWD 1300. But it's in a RWD Herald. How might it have been modified to achieve this?

Just bought the car, but it has history going back forever, and besides the Purchase of 2 off H4s and manifolds, the only change to the engine is to have the head skimmed 0.030" and hardened exhaust seats and valves installed.

Do you think that it would clear the tubular exhaust? Yes, I had thought about that. In a way it's a stepping stone from the first.

I have just purchased a 13/60, which has had quite a lot of mods. Among those are twin H4 SU Carbs. I consider these to be much too big for the engine and would like to get a/some carburettors more suited to the size of the engine. I see my options as (a) twin 1.25 HS2s, (b) a single H4, or (c) put on my Reece Fish carburettor. a) would seem to be fairly easy to source from a Spitfire. Does it matter what year/model. Any one any idea about needles. Apart from 0.030" off the head, I believe the rest of the engine to be standard. b) where would I get a manifold from to do this? c) this might be my preferred option, the Fish is a fantastic carburettor, but would require a manifold that would take a single 1.25" HS2 (Fish has same flange dimensions). I should probably mention that the Exhaust manifold is a 4 into 2 into 1 tubular type.
