Haven't seen a post about these guys before, so I figured I'd start one and see if anyone else has them 
Under colonial rule, the Egyptian police received these from the British government. They were chambered in a special tapered 12/14 gauge to prevent civilians from stealing them and using regular 12 gauge ammunition to revolt. This one had the chamber reamed out for 12 gauge (not by me) and has the rest of the barrel left in 14 gauge, so it acts kind of like a modified choke (dimensions are similar). My favorite part is being able to shoot a gun with the martini-henry action using cheap 12 gauge ammo instead of 577/450, or even 303 British if you get a converted one. I think I got it online for about $250, but that was a pretty good deal and it took a long time to find.
