Vintage 1/20 12k GF yellow gold charm bracelet with three charms!

This is soooo cool! I found this at an estate, and thought it was the neatest thing. The mailbox charm - the slot moves up and down, which is super cute. The "save the date" charm is about 23mm in diameter. The shield is about 7mm wide. It is vintage, so there are signs of wear. Marked 1/20 12k GF on the clasp. The maker is on the chain link and I can't quite make it out. The chain by itself is 5mm wide. Measures to be 7" long.
