Thank you Bob, and Michael, and Doug.
Doug found that 17H 4315 cross-referenced to 390333W and was common to Alfa-Romeos.
I also found on Google that 303310W, which is what I have, also fitted Alfas.
Michael has confirmed what the brake slave cylinder fits, and Doug has followed up with confirmation, a different BMC part number 7H 4584, and supersession numbers.
To muddy the water a bit more, two of my three 17H 4315 cartons contain Girling 303310W cylinders.
The third contains Girling 303300W So, on the face of it, different BMC and Girling numbers for the same part for our early BN1s, and wire-wheeled BN4s and BN6s.
They are all NOS in perfect condition. We now know there is supersession, but why? To me, they all look identical.
Who’d be a parts manager, eh? 😊
