The Edixa-Mat Reflex Model B-L has a focal plane shutter. As did all models after 1956, the Model B-L features internal automatic diaphragm actuation and instant mirror return. It also has an exchangeable prism. The "L" designation means that it has linear shutter speeds (30, 60, 125).
The lens featured with this particular Edixa-Mat Reflex B-L is a Steinheil 135mm f2.8 Edixa lens. It has an Edixa M42 screw mount and is designed to work with Edixa Reflex cameras. Wirgin mainly produced camera bodies, so they relied on outside manufacturers to make lenses for the Edixa Reflex cameras. A nice example of a vintage workhorse camera!
