hello there, I have recently inherited this firearm from my grandfather, i haven't taken it anywhere to get it looked at yet as i don't want it stolen out of my truck, it has numerous markings one either side of the receiver. trap door that flips to the right of the gun, seems to be possibly 45.70 size chamber with with rear "sniper sights". any help on this rifle would be great!
thanks!

thanks!
