I have had a Gowland 4x5 Aerial Standard for a while with no lens. It's pretty cool, but I'd like to be able to use it, thus a need to hunt for a lens for it.
Basically, what was the original lens for this camera?
This is the camera from Peter Gowland's site:

The focus is fixed, so it's important to pick a lens with the right flange-film distance. I can make a shim if it's close but can't do anything if the film-flange distance for the lens is too short. I have measured about 138.25mm depth from the lens board front to the glass with my cheap chinese digital micrometer/depth gauge. The lens hole is about 43mm in diameter as best as I could estimate as it's recessed and the fingers on my caliper were not long enough to measure something that recessed.
According to
http://www.cameraeccentric.com/html/info/rodenstock_3.html The 150mm APO-Sironar-N is pretty close (142mm flange distance and 42mm diameter) and has some visual similarities to the lens in the Gowland photo, the white lever with the dark triangle in it. The Symmars seem to have a dark lever with a triangle in it. The rodenstock also has the unpainted knurled lever slightly ccw from the pc flash sync. Any clues or suggestions are appreciated!
