Thanks Cornelio,

The Elgin document you referenced was Outstanding. It was a parts catalog of 1915. The mainsprings were listed but I was confused with the reference to steel, thick going, and thin going barrels. I did not know what a “going” barrel was?

There are several good items on this website, I wish we had material catalogs for all manufacturers and years.
The 1915 catalog did cover most of the Elgin movements which were used later as well – great reference.
