Quite a number of German companies purchased products in the former GDR (East Germany) and sold the items in the West German market re-branded under different names. Foto-Quelle, the largest photo retailer in 1970, did this with quite a number of cameras (more info). This specific model, the Revue ML, is a re-labeled Praktica MLT 5B by Pentacon. They produced more than 500.000 of it between 1985 and 1989. There are dozens of it for sale at Ebay, mostly at unreasonable high buy-now prices at 30 Euro and more, I got 2 for 12 Euro.
