The Welta Weltur (6x9) is a folding medium-format roll-film camera made by the German maker Welta Kamera-werke, producing 6x9cm negatives on 120 film. It was a pre-war coupled-rangefinder folder positioned in the mid-tier of the German folding-camera market alongside contemporaries from Zeiss Ikon and Voigtländer.

The single UK auction-hammer record on file shows a Weltur (6x9) selling for £200 in 2022, so the available evidence points to a value around that figure rather than a defined range. With only one saleroom result to reference, what a Weltur (6x9) is worth today depends heavily on cosmetics, shutter health and lens condition, and a clean, working example could realistically sell for more in 2026 while a tired one would fetch less.
