The Sector shutter has a single set of blades for shutter and aperture, is pneumatically timed, and was if I remember correctly introduced in 1904. I have one with a 210mm lens, mine is very early based on the 2000-something serial number, and still works well. It was replaced by the Excell shutter, which I think was mechanically timed.
