I recently bought a few 120 format reels on ebay, but 1 is slightly taller... while the 120 reels are 6.2cm tall, this one is an exact 7cm tall. other dimensions are identical. Can anyone tell me what format this is? I'm guessing its an odd kodak 620-type thing.

As soon as I can get my hand on a digicam I'll post a shot in the non-image gallery..

I should probably add this: these are stainless steel reels, not plastic.
