Hello. This is my first post, glad to be here. My son in law bought a Belgian folding trigger pocket revolver. It is a 5 shot with a 1.5 inch barrel. It has a solid top strap with an inscription on it. It has smooth ebony grips. There is a Crown over "R" over a five point star over "C" stamped on the side and what looks like a "70" on the trigger in 2 places. It has reeding on the front of the cylinder. I believe the caliber is .320 revolver. I am trying to find out who made it and when. Any information would be appreciated.
