A part like this is available from Edmund Scientific for about $40 by the
time you pay shipping. There is a shoulder in the way that prevents seating
of the 20mm lens. That will need to be machined back some but that is much
easier than cutting precision threads. /jim

I had looked for a few months on numerous sites and finally found one on
*Bay. I paid about $75.00 - $80.00 as I recall(in original box and looked
unused).
I made my own adapter that I like MUCH better, however, out of aluminum. The
RMS 0.7965", 36 TPI, 55º Whitworth threads are turned through a recess in
the main body. On a front protusion, or snout I turned the 49mm, 36TPI
threads for a typical front filter mount(approximately 3/16" above the main
body) so I can use the T-10 ring flash or twin T-28 macro flash with the
20mm lens that I use with the adapter. This adpater fits in an old OM mount
lens adapter of some kind that I no longer had any other use for. It works
GREAT!.
