Re the Hemingray-25, CD-175, and the question on how it was used. The complete Hemingray line is listed in the 1945 Joselyn catalog, and this is listed as a "SERVICE PIN". Regardless of how it is found in use, I have sketched the way it was probably designed to be used.

The Hemingray-60 and 60-A are listed side by side in these jobbers catalogs, and it would be helpful if traders would indicate which one, rather than just list them as CD- 257. Many collectors want both types.
