This is a question for original '73 RS experts (Robert Gross, GeorgeK, Rick Cabell et al):

What are the differences between original & replica RS Lightweight seats ?

Is there a way of telling whether a seat is an original or excellent replica (such as those available from RSL classic in Germany) ?

Any identifying features/markings on the originals ?

Thanks in advance.
