The Nagel Vollenda No.48 is a folding rollfilm camera made by Dr. August Nagel's Stuttgart workshop, producing 3x4 cm exposures on 127 film. It dates from the early 1930s, sitting in the compact-folder segment that Nagel specialised in before the firm was absorbed by Kodak.

Auction evidence for this specific Vollenda variant is thin: a single UK hammer result in late 2023 sold for £125, so as of today that figure is the only concrete reference for what the camera is worth at saleroom level. Hammer prices for these small Nagel folders are wholesale results (excluding commission) and sell for materially less than dealer retail asking prices, with condition of the bellows, shutter and lens driving most of the value spread.
