I bought an adapter from Edmund Scientific that has a thread to fit the
t-mount and has the RMS thread for the lenses. Unfortunately there is a
shoulder that prevents seating the 20mm lens and this will need to be
machined some. I think the cost of the adapter ring was about $40 with their
high shipping fee. Adding the cost of the t-mount makes this a "not cheap"
solution. /jim

Could the design be modified to utilize an Oly t-mount adapter? These
PM-MTob adapters are used for lenses that must be stopped down manually,
thus no need for any linkage for blades. Would save on cost of production.
Put me down as one that is possibly interested.

I haven't thought about it, quite frankly. It serves my own special
purpose. If there is any kind of general interest out there I could see
about tooling up to make several to lower cost. They are not at all
difficult or expensive to manufacture. I dare say I could have them made
and sell them for about what I paid for the PM-MTob adapter, or quite
possibly even less.
The down side is, the piece I made is replaces an insert to a lens mount
adapter I already had. This particular adapter requires an insert that has
a reverse 15º bevel on the camera side that fits in a 49.5mm hole in the
body of the adapter which is then secured with three small screws @ 120º.
I don't necessarily have a resource for the OM bayonet mount portion.
Those would be $$$$ to produce unless someone has a line on them, or can
get a bunch of used ones that are all identical. Otherwise each insert
would have to be custom fit to the individual adapter and would be
accordingly more expensive.
If there is an interest, and a resource can be found for a common OM
bayonet adapter, I would be willing to produce these to just cover cost,
what little effort and time that is spent, and shipping.
