This is currently on eBay (140293558714). The mount bolt pattern is different. Is this from an NRS or earlier?
I sent a note to the seller, but they did not reply.
Note also that the Pre-Ts did not have a flywheel magneto. That was one of the real selling points of the T -- it did not need a battery. The A, B, AC, C, F, N, R, S, & SR all came with some type of battery -- either dry cell, storage or in some cases both to power the coils. The K had a battery ignition as well as a high tension magneto system. For the other low priced Fords the high tension magneto was considered too costly. Although there are Ford factory drawings for a high tension magneto for the NRS along with the brackets to mount it -- but to our knowledge it did not go into normal production.
By the way you are doing great on the T knowledge -- that part was just outside of your area. (And I didn't know what it was either. One of the things I like about the forum -- it is a great place to learn about Ts and things that look like T parts. Thanks Peter for the ID.)

Thanks for the additional detail information (I always look forward to your posts - It's like an extension course at "T-University"). One of the things that puzzeled me was the oval coils which I know came later in T production.
