TACHOMETER,BSA 3-1 BLACK
Black-faced tachometer with a 3:1 drive ratio, cataloged for BSA use.
This listing is for a 19-8950 tachometer, black-faced, showing a 3:1 drive ratio, and per the catalog description it's cataloged for BSA use rather than Triumph. If the manufacturer tag on your parts book points you to Triumph, don't go by that alone — the description on file plainly calls this out as a BSA-specific piece, so check what your bike actually calls for before you order.

We don't have much more detail on file beyond that basic description, and the part hasn't shown up in our catalog history under this number very often, so we can't speak to specific fitment years or cable/drive compatibility from what we have here.
If you're trying to match this to a particular BSA model or drive setup, give us a call and we can talk through what you've got before you buy.
Sorry if we got something wrong here. If you think this information isn't correct, .
