The Kershaw Patent Reflex Tropen (Tropical) is a tropical-finish reflex camera, built with the teak-and-brass body construction characteristic of tropical-model cameras intended for use in humid climates. It is a collector-grade item rather than a working tool by today's standards.

Auction data for this model is extremely thin: a single UK saleroom hammer result is on record at £868 in early 2021, which serves as the only available reference point for what one is worth today. With just one data point, it is not possible to quote a reliable price range or median, and any future sale could land well above or below that figure depending on condition, completeness and bidder interest on the day.
