The Graflex KE-4(1) is a 70mm military combat camera, built to US armed-forces specification for press and reconnaissance work. It is a roll-film system camera using perforated 70mm stock with interchangeable backs, sitting well outside the consumer market when issued.

Auction evidence for the KE-4(1) is thin, with only two recorded UK saleroom results, both from November 1998, where hammer prices ranged from £440 to £480 (median around £460). As of 2026 the model trades infrequently, so today's value is harder to pin down than for mainstream cameras, and condition, completeness of the 70mm back, and presence of the original lens are the dominant factors in what a clean example sells for.
