W&H DuCoil Distributer

I have a vintage W&H DuCoil distributer. The model # is 2JC. Does anybody know what kind of an Engine a 2JC DuCoil Distributer is made for?

Thanks, Geo

I believe that the 2JC part of that reminds me of something british... MG? Triumph? I'm pretty sure my old boss's Mk1 spitfire used a 2JC coil, but I'm not sure of the DuCoil name.

I made a mistake on the model #. It is a 1JC, Sorry

This thing is a distributer not a coil.

Ah, sorry... a google search picked up several for "1JC distributor" including some direct references.
