Hello, I am looking for help in identifying make/manufacturer and year of this antique pistol. If you look closely at the barrel area below the hammer there is a R stamp and another circle with some symbols. It's hard to make out maybe an E L C and a star? From my limited research and from...

Does anyone recognize these markings? This is on an over and under percussion cap pistol which I recently acquired. Any assistance would be appreciated!

This is a family heirloom of unknown origin. Could have originated from navel links. The only markings are shown in the closeup photo. No brand or country of Origen can be identified. Looking for any info like age, origen, purpose, value etc. Any help much appreciated.
