Hi Brian, ich think so too, but ich have a friend, he has a man in nederland, he is a specialist from yamaha europe, and, perhaps, he can help. He is very good in history of yamaha.  I have send the picture to him, so he can ask him. We will see, what happen.....

The Problem , of the number, that do not match, with the normaly typ number, of the TR1 5A8 will be,
that you must change the frame.  Frames, with paper´s are no Problem, i have any frames with legal papers, but  i think, the best way, is, the Machine let, as shown ! It´s really rar!

When i have answer, i will tell it you quickly.
