Magnus Niéll - Vest-Pocket Camera, 1908/11/17 (Advanced Version of the Expo Watch Camera) (350Kb)
Camera designer Magnus Niéll applied for this patent in 1907. It was granted in 1908. Unfortunately this improved version of the Expo Watch Camera was not manufactured for sale. This is an attractive
design that among other improvements, features a built-in folding reflex viewfinder.
