Another Searle proto type appears to have surfaced.
"This Searle prototype is fascinating as it has features consistent with Searle's 1905 patent drawings which were dropped during the development of the Model 1907. The slide serrations wrap all the way around the top, the magazine release is immediately below the trigger guard, and the grips are secured by screws. Significantly, as seen in the patent drawings, the slide is secured to the frame with a sprung latch in front of the trigger guard, a feature which would be extensively re-designed for the production models. It was found by one of Searle's descendants in his desk and is an intriguing and Rare piece to add to any collection."
