The Graflex No.3A is a large-format roll-film press and field camera from the early twentieth century, built around the 3A postcard format (roughly 3¼ × 5½ inches). It was positioned as a professional press and reportage tool of its era, typical of Graflex's focal-plane-shutter hand cameras.

At UK auction today, hammer prices for the Graflex No.3A are thin and condition-led: recorded results sit between about £80 and £130, with a midpoint close to £100. With only a couple of saleroom data points, what a No.3A is worth at any given sale depends heavily on completeness of the body, shutter function and cosmetic condition, and clean outfits tend to sell for the upper end of that range.
