Just got one of these cameras, looks great, but unlike my other cameras with large format style shutters, I cannot seem to find a switch on the shutter to open it up for ground glass viewing.

On my Fotoman 45SPS, I can flick a switch and the shutter blades open up, allowing me to compose on the ground glass. I can't see this on the Graflex, so only option is to use the Bulb setting to hold the shutter open for ground glass viewing. If that's just how it is, fine, but I wonder am I missing something?
