Two vintage Scottie dog pins

Two vintage Scottie dog pins. The top pin features rhinestones. I think it’s from the 1950s. It’s in fair vintage condition. The clasp works. The metal shows wear. Many of the rhinestones don’t look clear anymore. There are two rhinestones missing from the hind leg and one missing from the front shoulder. There’s a maker’s mark on the back, but I can’t tell what it says. The bottom pin is in very good vintage condition. The clasp works. There are no significant signs of wear. I’m not sure which decade it’s from. From a smoke free and pet free home.
