1963 BSA A-50 Revolution Counter
« on: April 10, 2021, 04:56:08 PM »
A RMS 3003/02 tachometer is listed for the 63 BSA.  What is the drive ratio of that tachometer?  And any suggestions on where to get a refurbished 3003/02 tack?

I don't know about genuine refurbished, but ebay's offerings are always worth a glance.
If only to confirm the massive prices for genuine these days.

There is always the el cheapo replica variety. says its 3:1
 "A quality reproduction of the Smiths clock RSM 3003/06"  whatever that means.
