Note 2: Unlike later Polaroid rollfilm camera models, the 95 has a pair of clips in the film chamber to hold the "negative" roll in place.
And NO, other then 55 type, there was no negative, people could do a transfer before the emulsion cured, (off the print and off the neg side), and it was a sodium sulfite bath thst cleared the negetive, ie, an "alkalie"...AND let's not forget that really old Polaroid cameras used Polaroid roll film, the pack film was the "modern" peel-apart.
An alternative to Polaroid roll film that may or may not produce photos is to adapt your Polaroid Land Camera Model 150 to the kind of film you can still get fresh. Because the size of the film chamber will accommodate it, you can create a roll film adapter that will allow you to shoot 120 or 220 film. You may need to drill holes on both ends of the camera to accommodate spool holders and a wind knob. On the left side of the camera, you will need to do this at the bottom because the viewfinder is in the way on the top. You also will need to seal the hole where the instant film once came out. You also may need to guess about where each frame on your film will be since the camera was not originally designed for non-instant film. As an alternative to traditional film, you may want to combine a lesser Polaroid camera's pack film chamber into your 150 to use the kinds of instant film still manufactured although not by Polaroid.
Notes: The shutter mechanism on this camera is rather unusual in design, and consists of a slitted rotating disc which is controlled by a pneumatic cylinder. The meter cell controls a vane which in turn regulates the flow of air from the cylinder, thus allowing for a range of shutter speeds. The mechanism used in the J66 and J33 cameras is also similar to that used in the #440 Photoelectric Shutter accessory that was available for most of the other Polaroid rollfilm cameras.
There's a store called Rare Medium in Seattle that specializes in old Polaroid equipment, and the one time I stopped by I noticed they had an old Polaroid roll film camera (forget the model) which had been converted to take pack film. Store's contact info is on their web site: . I would guess someone there would know who converted the camera they had for sale.
