Tom said about the Oly 4/3 lens mount picture here on page 4:

Bring that same page up while holding an OM body.  Rotate the OM body 45
degrees to the right.

Compare the two.

Tom is right!!! It is clearly an Oly mount. Rotated 45 degrees all the bayonet claws match up in size and position. Then if you recall that I quoted that page as saying:

"However, with the Four Thirds System, in contrast to 35 mm film cameras, the diameter of the lens mount is designed to be approximately twice as large as that of the image circle"

Well, the image circle on the 4/3 sensor would be 22.5 mm in diameter. Twice that is 45mm and the inside diameter of an Oly mount is 47mm. That seems pretty close to "approximately". There is hope yet!
