This is a used Lucas magneto insulating washer – part number 2192.
It's designed to fit classic British motorcycles like Triumph, Norton, and BSA.

Since it's used, it may have some cosmetic wear – maybe a bit of discoloration or light scratches – but it's still fully functional and does exactly what it's supposed to do: insulate the magneto properly.
