Smiths Oil Pressure Gauge circa1960s or earlier

As seen an original oil pressure gauge that was fitted to British cars I think fast cars at that.

Unfortunately I couldn't find an exact match on Google image search or through research.

My best match was it came from a Jaguar, MG, Aston Martin & Triumph or similar but if you know then please tell me I would be very interested and grateful.


Apart from slight rust all parts are there and I will package it up carefully I know these are worth a bit.
