A Victorian parts hoard

Wish I had some provenance for this lot that I picked up some years back. Bought it pretty much as scrap silver, and it mostly consists of parts of American mid-19th century dip pen and pencil combinations.

No maker's mark on anything, unfortunately, and nothing quite distinctive enough to pinpoint a maker. Early examples of this sort of combination were made by Bagley, but many are also found with Fairchild imprints -- and others with no imprints at all. By all appearances the hoard is an old one, all from one factory, perhaps rejects or old stock set aside to be sent to the melter and then forgotten.
