Absolutely... the 65....
does NOT cover the larger pack film polaroid size. It is an earlier lens, coming out in the era of the earlier Press and Super 23 bodies. The Universal Press takes pack film Polaroid backs and the only lenses that cover the 3x4 inch (near) pack size are the 50, the 75 and the 127. All the other Mamiya Sekor lenses are limited to 6X9. Furthermore, the 75 and 127 lenses originally were produced and mounted in the focus helical that uniquely mounts to the Polaroid 600SE. Later, Mamiya started mounting those lenses and a 50 in the Mamiya Press breechlock mount. (the later 50 may cover the Polaroid format, but I have never seen it mounted for the Polaroid 600SE)
You have to be careful when purchasing these focal lengths since the mounts are NOT interchangable. Both Polaroid and Mamiya contracted for the separate mounts to protect their own lens sales, although Mamiya made all the cameras, mounts and lenses, and branded the Polaroid 600SE components for Polaroid under contract with the different mounts.
The 65 was never mounted in the Polaroid 600SE mount, as it does not cover the format.
It's not uncommon to see eBay and other sellers stating that the lenses and other components fit both the Universal and the 600SE. They absolutely do NOT.
