I met a chap in Amsterdam a few years back, he had made his own out of this and that, the front end off a Speed Graphic I seem to remember. He'd been in the business for over 40 years, and been all over Europe, and then some. He was quite adamant that these cameras were not particular to Afghanistan, nor did they originate there. The term was an undeserved lable. They were once quite popular all over the world, in different shapes and sizes way back when. But have since become rarities, used mostly in the more depraved parts of the world, or as tourist traps in e.g. Amsterdam.
Have considered building one at some stage, but not sure my fingers are up to being soaked in fix all day long
