It sounds like a t-mount. If it is, the inner threaded portion should
be 42mm diameter.

I have a mount - but I'm not sure exactly what it is. It came off of
an OM-4 that was used in a lab, presumably on a microscope. It says
"for Olympus OM" on the front, flat surface. The inner portion is
threaded. It has an automatic open f-stop connection (meaning that
it actuates the camera in a fully "open" aperture setting, and holds
it there, so that the aperture can't be adjusted. Anyone know what
this might be used for?
