Regarding the FD: I think it's somewhat common that people see the larger front clamp and assume GS. However, the GS FD had steel actuating arms that were thinner (and heavier) than the forged alloy of NR and SR. The smaller clamp came later on and was used on both NR and SR.

This is a post-CPSC NR.

I'm taking pics of the frame details right now, so I'll have some more on this project in an hour or so.
