Doesn't look like a Commercial View. Looks like a 5x7 Watson. Nice camera, I have one. You might have to fiddle with the rear extension to get the gearing correct between the two pieces. All other info is correct, the knob in the middle of the front standard is for shift, the sliding stop on the front of the standard slides down and lets you do swings. The back has all movements also, but the lockdown on swing and shift is a little flaky.
It does make up into a nice compact package, but is a bit heavy.
