It was sent to a company in Michigan called Precision Power Inc. 

Taken directly from their website: "We are specialists in the auto electric service industry, primarily servicing the specialty or unique applications that most rebuilding shops don’t have the experience or capabilities to service properly. We place a special emphasis on the repair and restoration of antique, special interest, vintage car, truck, tractor and marine electrical units such as: Starters, generators, alternators, starter/generators, distributors, magnetos, voltage regulators, switches and various DC motors. Whether your needs are a simple repair or a complete Concours restoration, we are equipped to serve you with expert technical knowledge and unparalleled craftsmanship, with special attention to detail that is second to none. We have a vast reference library of technical and engineering data for antique and classic electrical systems dating back to 1909, which gives us a depth of knowledge and capabilities that most shops simply can't offer." 

I sent it over, and it took around 20 months for work to be finished and the item to be back in my hands.  

This and a distributor (will also be listed) were rebuilt with the intention of using them on my restored 1941 weapons carrier. However, circumstances changed, and now they are both up for sale.
