Oh, look. Wikipedia, the world's most trustworthy database of information that can be easily edited by anyone and everyone who thinks one thing might be wrong so they change the entire article because they're too thick in the skull to accept they were slightly off on one truth. I'm not making accusations, but Wikipedia is really only a place to get some base knowledge, which you should then research on more trustworthy sites such as
this one. Notice how there is no edit button anywhere..
Reading further on this site, I concede that you were correct it was designed by the IWI. However, there is nothing said on who actually manufactures it.
