I'm selling five Leica-fit lens flanges, originally part of Leica-NEX adapters which I modified to make custom lens adapters. I've marked them as used since they have been pulled from the adapters and have faint marks left by the grub screws that held them in place, but they are otherwise as new. They ought to be useful for e.g. making L39 adapters for other cameras, adapting lenses with this thread to bellows and other macro gear, etc. There are some very good camera and enlarger lenses with this mount and it might be a good choice for anyone building their own camera etc.

The internal thread is theoretically 39 mm in diameter with a thread of 26 turns-per-inch or threads-per-inch (tpi) (approximately 0.977 mm pitch) of Whitworth thread form. In practice there seems is some variation and this may instead be the Russian equivalent, M39×1 (39 mm by 1 mm DIN thread) - there's very little difference for most purposes.

Dimensions are approximately
Thickness - 5.4mm
Widest Diameter - 48mm
Diameter in tapered section - 46.6mm
I've measured them with an old style vernier caliper which may not be incredibly accurate.

As usual I'm starting low and with no reserve. See my other listings for more photographic items.
