Great NOS find! The kit was for the 9N-10000-C generator. When the 2N-10000 generator was released, the bracket was included but bolted to the body with two 1/4-28 hex bolts and the wrap-around band deleted. The 9N and 2N generators were virtually the same. If you have two tapped holes on barrel, it is the 2N model.
