Delco-Remy American Bosch Aircraft Magneto Spec # AN-9511 Type S89R03. Condition is unknown. I have know Idea what to price this part at. It is a beautiful antique looking part. If anyone has any information about this part would be greatly appreciated. This was in the extra part’s bin stored in the T- hangers. I am sure this was floating around Central Aviation since before 1971 in accordance to one source that worked there back then.. Central Aviation is an FBO aircraft restoration in Watertown Wisconsin. It was closed more than Five years ago. Thanks for your interest. Hope you find what you’re looking for.
