I've had this speedo a long time, it's been restored (poorly) it has a resetable trip with a remote cable to operate. I've always wanted to know if this is a Smiths made part of something home brew.
It shouts Caerbont to me. I have 3 original Smiths trip speedos if you want to see the real thing, a silver 90, a Cooper 100 and a Cooper S 120. These are part of my collection and not for sale.
I think that the silver 90 was equipped on the early Austin works minis.
Cooper S 120 have aluminum black ring.
Could you post front/back pictures of these speedo.
The finish on the back of the gauge is not what i would expect for a factory unit, the reset cable looks well used, and the fuel gauge is the later type. However, what makes you say it was poorly restored?
