Does anyone recognise what part number this is? I'm guessing it is a Girling part, maybe. I don't see an obvious equivalent part on the usual websites (Melvyn, Gomog, BH).
Notes: This is a single-circuit brake system, the red arrow is the line coming from the brake master cylinder and the green arrow is the line that goes off to the 4-way junction with the brake light switch.
Many thanks...
