Tiny Perfume Bottles

I love things like this! These are silver( I believe) perfume bottles, and I only know this because one still smells like perfume! The silver is just a decorative cover over a little glass bottle, both being completely intact. My dad found them out in the middle of a field that he was farming! (Now I want to go dig around there more!)
The larger of the 2 has some sort of shield mark on the bottom, with what looks to be an MC next to it, with letters that I cannot make out around the MC.
The smaller has a RM on the bottom, slanted in like so, /\, a 0925 across the top of the RM, maybe hech down the left side of the RM, and an O.F on the right side. The right side and underneath have characters that I cannot read. Underneath the RM there is an me, then unreadable, and what looks to be the word sterling under that. Both have similar leaf patterns as you can see from the photos. I am extremely intrigued by these bottles, so if any one knows anything, I would love to hear it!
Thank you!
