The Glunz Model 40 is a vintage camera offered by the German maker Glunz. With limited public technical documentation available, it appears in the UK secondhand market as a collector-oriented item rather than a working tool.

Auction evidence for the Glunz Model 40 is thin: a single recorded UK saleroom result from December 2021 shows a hammer price of £25, which gives a rough indication of what the model sells for at wholesale auction level rather than at dealer retail. With only one data point, today's value is best treated as a guide, and a clean, complete example could realistically achieve more or less depending on condition and bidder interest on the day.
