I have that info. The generator is the middle section of the body where you advance and retard the initial timing. Has nothing to do with generator as in charging system. I was hoping to find some vintage info from bitd. Based on the riveted tag I would have thought this to be an early Mallory performance piece but maybe not.?. Thanks for your help none the less. This might end up being behind the bread box on a little 306 at some point.
