There's Park City Engine No 9, limited edition #1405 out of 1775 dated 1984. (This one has rust on the back.)

Park City, ice cream & balloons, dated 1896, #261 out of 2500,

Park City Queen, dated 1983 showing a paddleboat, #2608 out of 3500, signed M A Ricker, and 

Park City Carousel from 1984 showing the carousel, #2219 out of 2500 signed as well.

There's some rust prominent on the back side of the Engine one and a little on the back of the river boat. The Carousel is the most worn particularly at the bottom.

I've included closeups of the buckles, front and back.  Sadly, the artist is no longer with us.
