Here's the answer I received from Mr. Dethlefson: "I'm afraid that the information you want is at the Edison Historic Site in New Jersey and the Site is closed for renovation. What you want will require a trip to NJ and much digging in the archives when the Site re-opens. Best wishes, Ron" I had asked him additionally about the number of takes Edison might have required for BA production, so it sounds like maybe there's a chance there might be more than one take available on BA 5011 as well. Again, does anyone know what Edison's policy was regarding the BA's? And do BA's have take numbers hidden anywhere on them?
