Hey all. I’ve got an old Iver Johnson double barrel I got from a buddy who inherited it from his father who’s passed. Now, I’m a hobbyist who dabbles in restoring guns and he gave it to me to take a look at. Upon opening it up, I realized how over my head I am. It’s a box lock (which im not familiar with to begin with) with Hercules on the side. Made in cobourg. If anyone has any idea on how to disassemble/reassemble this thing you’d be a life saver.
