Long M39 Extension Tubes
Canon Made sets of internally Flocked 75 and 200mm M39 Leica Thread Tubes.
I have no idea of their original purpose, but they seem to have potential again, as suggested.
Comments welcomed,
Len

These are my favorite tubes.

Canon made a range of these from 20mm to 200mm for the M39 rangefinder cameras. I have a box full of these. They are very well made and useful for all kinds of setups but the diameter can be a little narrow.

They made a earlier glossy finish and a later matte finish.

I have the early boxes for some of these and back then Canons colors were blue and white, none of the red that you see now.

Don't overpay for these. You can usually get these for $20 a tube max. I know I have more than a dozen.
