You see the same type of errors on the Citadel firearms as you see on the Khyber Pass fakes and for the same reason. While English was the language of government in Egypt at the time, it wasn't the language (or alphabet for that matter) of the workers. So not knowing what a "C" was supposed to look like, it got applied incorrectly. From the limited number of Citadel firearms I've seen mistakes are fairly common. But of course unlike the Khyber fakes, these are real and very collectible firearms.
