Another question. All things being equal in the good condition of the silver on the semi-silvered mirrors, which was brighter--the top mounted Graflex beam light or the Kalart Focuspot on the side-mounter Kalart finders? Didn't the Graflite run off 4 C cells for a total of 6 V, and therefor the Focuspot was a 6 V bulb? ( I don't own a Graflite any more and forgot what it took).
