The Grass & Worff Convertible is a camera produced by the German maker Grass & Worff. Public technical detail on this model is limited, so its format and configuration are not described here beyond what the auction record confirms.

Auction evidence for the Grass & Worff Convertible is thin: a single UK saleroom hammer result from November 2020 saw an example sell for £850, and that figure is the only reference point for what the camera is worth today. With just one data point at auction-hammer level (wholesale, excluding commission), it is not possible to give a reliable price range or median, and condition, completeness and bidder interest on the day will swing any future result substantially.
