I was wondering the same thing.
Regarding the band (bracelet) is the one on your dads original? If so, I would want to try to restore it as I dont believe that the original bracelets are available and the current style is different from what they used in the 60's.
Last thing you want is to spend all of this money on restoring a classic piece and then have it look like a new one. Kinda like hanging a 964RS tail on a 73 RS.
