Here are some dimensions and descriptive comments for this lens:
It weighs 10 lb 13 oz. Diameters: objective end-ring 5.125"; mount end-ring 5.250"; length 8.312". Mounting is 4 lug bolt-flange, with 6" bolt centers, sized for 1/4" bolts. Manual focus achieved by moving two opposing screws through perhaps 80 degrees in spiral-cut slots in the barrel; this moves the focusing element(s) a longitudinal distance stop-to-stop of about .315". External optical surfaces appear to be coated. The (6 X 3) is white-stamped near the mount flanges.

I have no off-site image-hosting available, but I'll be happy to email pics, and answer questions, for anyone interested; just send an email address to:

Thanks for looking! wlw
