Vintage navy leather frame bag gold / brass kisslock 60s

Vintage navy leather bag with shiny gold / brass kisslock. Frame bag, large ball kisslock closure. Lined. No tags, there's a spot where a tag used to be so I can't tell the designer. Reminds me of Bonnie Cashin pre-Coach style, but I don't think it is. Probably 60s, could be earlier. Bag measures about 7/5" across by 8" tall. Fits my iPhone Pro Max easily. Strap drop is 19", it's a shoulder bag. It's in great vintage shape, no major flaws that I can find, no odors. Beautiful and classic.
