Hi
Thanks for your interest....No there are no other markings on that we can find...We found just that one EA number by luck....we have looked pretty thorough on it.....
This starter was found in my Uncles garage....I was told by him it was off of a round engine.....there are some numbers on it...EA-94304 or its EA-94804......then someone told me it was off of a WWII aircraft.....I would really be interested in some information if you have some....I have no clue...
