House of Clasps by: RTL-JewelerToTheStars
This is a "House of Clasps" piece. We have been in the business for 40+ years. We have a ring with the same hallmark that we asked our GIA Graduate Gemologist appraiser about and he said it is commonly mixed up with Honora. You can check out the ring at our eBay page at :
I own a Pearl clasp from c1940 or c1950 that also has this identical Hallmark.
From what research I have done, I have concluded that what I have and what you have here is indeed a "Hagerstrom & Chapman" clasp.
P/S. Here are links to a few pictures of other clasps with the same hallmark, two of which have been identified as Hagerstrom & Chapman.

If not, at least we know we gave the same "family" of origin for our clasps.
