Hello, I came across this SMITHS speedometer in a box of parts that came with a car I bought. It appears to be from a Vincent motorcycle but the number on the face (S.576) is missing the L or K at the end. So I’m not sure if the Vincent origin is correct. It measures 5 inches across.
Anything that I can find out about this gauge would be appreciated. Not trying to sell at this time, I think it’s cool and just want to know more about it.
I can’t load any photographs from my phone for some reason so I hope the number is enough.Thanks

Edit: Discovered that is indeed from a Black Shadow

I think the 5inch speedo (as such) was originally fitment to Jaguars, the Vincent variant (of the Jag guts) had a specially cast aluminium body.
An original Vin fitment had a right angle gearbox at the cable entry, the gearbox was retained by a screw into the speedo body (this is usually a giveaway for determination of 'OEM' versions.
The Auto Tempo versions did not use a gearbox and the drive cable connected straight to the speedo and did not look so 'for the job' as the originals.
I seem to vaguely remember something about the AT version only having one light (the originals had two), but that may just be old age playing me up!
