Praktika B Winder
First generation Praktica B Winder bought (new) for 630F on march 23rd, 1983.
This model is contemporary of the first “B” cameras, with on the back a plate of “squared grenade” sleeving (replaced since a long time by leather!) slightly different from the bodies'sleeving. Made in Japan. Fed by 4 LR6 batteries behind a screwed lid (on the right on the image).
