Frank,

Have you tried 'dashto.com'? Tom Mister has a lot used and NOS parts. His site has a search engine to help find what you are looking or you can email him. Also try Uncle Larrys in Canada.

From what I can see in Swiggart, The 974 needs the following combination in a complete Hairspring:

Hairspring: #386
HS Stud: #607
HS Collet: #76

*note* these are Hamilton Factory Numbers

Most of the 16 Size Grades used this combination EXCEPT THE FOLLOWING Grades which used a different combination:

992E, 950E, 950B, 992B

Thanks for the information Mike. I wish Swiggart was still in buisness,life would be alot simpler.
