What I do know is it was in a box labeled Bantam - Continental Engine. And it was purchased in 2006 (as I will provide a picture of the original receipt) from a company in Chicago that seems to specialize in "Continental IND Engine Parts". It does not look to be used at all but it has been sitting on a shelf so it may have shelf ware. Please review pictures and please ensure this will meet your needs, as I dont know a lot about this item I would be happy to provide any additional pictures or answer any questions to the best of my ability.

Thanks for looking.
