Mystery Cam

LOL. I posted what it is earlier, I just sold one identical to it last year. Lay it next to a LA/SBM cam and marvel a how the lobes are not arranged in the same way. It's not going to run in ANY 318 but a Polysphere. Look up the part number I listed above in an old Isky catalog (from the 1970s, maybe early '80s), that's what I did to identify the one I had.

Now you are beginning to see my frustration. ;)
