Typically, Polaroid used 127mm f4.7 Rodenstock Ysarex in a Prontor SVS, or, or a 127mm f4.7 Yashinon ina Seikosha shutter, both slim Tessar type lens only protruding 3 or 4 mm from the face of the shutters. Very early US models used a similar sized Wollensak 127mm f4 in a Rapax shutter.
These thin lenses allowed the original Polaroids to fold, there's no chance with a 150mm Symmar S they only just fold away into much larger (deeper) 5x4 cameras. There is a second factor, the front standard fitting has to be adapted for the longer focal length lenses, and thirdly a 150mm Symmar S is quite a bit heavier.. So the Litman;s were made to be rigid
Dean Jones/Razzledog added various lenses, one that was popular was the 90mm f6.8 Angulon, this could fold away. Early post WWII 90mm Angulon lenses had a reputation for inconsistent quality, one reason Linhof started testing then selecting lenses. By SN 5,xxx,xxx Schneider had resolved the issue.
Running the repair shop for an Austalian camera store, Dean had noticed the tube lengths of the early poor 90mm Angulons were inconsistent, he would strip the shutters down completely and machine the casing to the correct tube length. That resolved the sharpness issue. A QC issue at Deckel/Compur rather than Schneider. In the months before he passed away, Dean was trying to compile a spreadsheet of these 90mm Angulon's Tube lengths. It was a Compur-P #0 shutter not used for any other LF lenses.
