Kodak Ltd (UK) always sold Graflex cameras with British lenses, look here for details of the lens. It's a pre-war fast press lens for quarter plate, it won't cover 5x4 and it probably won't be as sharp overall as TT&H (Cooke)'s slower lenses.

It's possible Eaastman Kodak also used Cooke lenses but I'd guess the camera was taken to the US from the UK or a colony.
