Balda Dresden Analogue camera

La Baldina and the Super Baldina were a series of cameras produced in Germany by Balda Werke from the mid-1930s to the mid-1950s. These cameras can be quite confusing for collectors, because the original basic camera body was improved and marketed under more than a dozen different names by two different manufacturers (both of whom used the Balda name for a period). To make matters even more complicated, the Baldina name (and Super Baldina) was used on two very different camera body series. The cheaper variants tended to have 3-element front lenses with Prontor shutters, while the more expensive variants had unit lenses with 4, 5, or 6 elements and Compur shutters. The camera is not working with the lens locked; a collectible piece nonetheless, and if refurbished it could still function."} }} }? Wait remove extra. Ensure proper JSON.
