This fabulous display was put together by Bob Stahr, Hemingray historian, collector and digger at the Hemingray factory. I believe he told me this opaque purple milkglass spool with iron clamp hardware was dug at the factory! So was the unique aqua spool that appears to be cut in half. Bob has the other half on the other side of his display. My guess is they were held together with a similar hardware as the milkglass one.
I decided to focus in on some of the more unique pieces in his display rather than take a group shot which would have been hard to appreciate from a distance. You really have to see these spools in person to truly appreciate how amazing they are! :-)
