a few variants existed: a cargo van (letter f - "furgon"), a minibus (letter m) and an ambulance (letter s), and some others. a rare variant was made in the form of a light truck. at the time, the nysa was practically the only van-size ambulance used in poland. many vans were sold to the militia, which was the only form of police during the communist era in poland; blue nysa vans became a kind of "trademark" of the militia (militia variants had slide doors on both sides, most had also a two-part door at the rear).
