since we're on the topic of guns....
my dad gave me this the day i turned 18 and told me he'd explain the story behind it when i turned 21. of course my mom took it from me and hid it immediately

he passed away before my 19th birthday and i forgot about this until my mom gave it back to me today, and id like to know if you guys could help me ID it, i know its a cap and ball gun but thats about the extent of my gun knowledge. all i know about the gun is what my mom knows, that he "came home with it after a weekend out with the dune buggy guys in the desert." this was back in the late 70s right around the time i was born.
these are the only markings i can find on it.

im guessing its some sort of replica but any info you guys might have would be great thanks
