I bought a Gowland Pocket View new in the early 80's. It was marketed by Calumet and was the simplest (and lightest) of the many variations it came in. Two 6" rails, only swing and tilt for the back, all the movements in the front. About 2.5 pounds with a 150mm f5.6 Caltar IIN mounted on it. Mine has a bail handle and I have used a Calumet roll film holder (6x7) with it for color work.
Many variations, as I mentioned...I think it depended on what parts Mr. Gowland had lying around. He made versions with all movements, various types of backs, 6"/8" rail and two 8" rails. Mine was originally set up to have all the movements loosened and tightened with an allen wrench...I replace some with knobs. The cameras can get up to 3.5 pounds or so w/o lens if it has a heavier back, 16" bellows and big knobs.
It is a camera one either loves or hates -- I love mine. No indents, for example. Not a precision instrament, but a very useful tool. I have backpacked many times with it (11-day solo trips into the Grand Canyon, for example) and bicycle toured for 6 months with it in NZ.
Not extremely sturdy -- the trade off for being light-weight. But sturdy enough. The bag bellows would be for use with wide angle lenses -- unless you plan on using 90mm and shorter lenses all the time, a standard bellows would be better. The standard bellows should handle a 90mm easily...might even be able to handle a 65mm, but I am not sure.
Usually the camera comes w/o a lens -- add that to your cost. Occasionally I see a used Gowland Pocket View on eBay, but not often. Used, you should be able to pick one up with a lens for $1000 or less.
Anything I missed?
