I would rather see a better watch than a 100% perfect rep, i once help on the build and resoration of a BSA C11 bike, we built it with TI fasteners an improved it where it could be with in the style of the vintage and with modern materials, some purist complained, Another time i worked on a 1920s harley with a chair, the owner wanted all original parts even down to the fibre wrapped wire what a pain it looked good but was not a very useable bike,
An improvement is never a detractment!
