Brian, thanks for the patient explanation.
Funny, I'm acquainted with Jeff Goggin, although we haven't communicated for years. Per Google, his e-mail address seems still to be email@example.com. Why don't you ask him whether he'd use a Galvin for your application? His review makes it sound iffy, also makes me regret that when I started thinking about moving to 2x3 (around 1988) I didn't get literature from Galvin. Back then it seemed too hard to set up consistently to be worth pursuing.
BTW, www.cameraeccentric.com has a 2x3 Galvin brochure and a 1988 Horseman catalog.
This http://www.ebay.ca/itm/CAMBO-SC-1-6x...item5895820964 2x3 Cambo SC has been on offer off and on for the last year, you might ask the seller whether he still has it, also whether it has a bail or international back. Unfortunately the Super Cambo catalog on cameraeccentric doesn't report on movements. If you're seriously interested, I can take mine out and measure.
