Hampden Watch Material Catalog 1923 Edition - reprint

Hampden Watch Material Catalog, 1923 Edition, reprint. Catalog is 8 1/2 x 11 and is 45 pages long. Catalog and price list of parts, surprisingly useful if you work on watches but not a guide you can use to identify movements as there are no movement drawings, just a list of factory parts. Images do a pretty good job of representing the item.
