We may make a Rover 12 P2 ( 1936 -1948 although not sure whether all had reserve valves, certainly later ones did) New Petrol Reserve Valve with the larger diameter 4 hole flange.

Made with our new 4 hole bodies, these are machined from an alloy billet & anodised for ethanol proofing, supplied with new gasket & special petrol proof sealant.
