0-100 PSI full sweep replacement mechanical oil pressure gauges; does not include piping and engine fittings. Black version has the angled "half-V" bezel that matches the bezels found on original Mk1 classic Mini gauges, so for Mk1 restorations this might be the one to use, even though the 270 degree sweep face was not original. Magnolia face version will not match Mk1 Minis angled instrument bezels. Made by the licensed Smiths manufacturer. Ref: SIB521, SIB521MG, PG1310-00C, PG1310-01C.
