Spotless Spotmatic...

When I found someone local giving away a Spotmatic (albeit with no lenses, just a microscope adapter and some extension tubes, I was pretty sure that the camera was either really beat up or had something screwy. I was wrong. The thing is SPOTLESS (aka in mint condition) and the shutter fires properly at all speeds from 1 second to 1/1000. Even the self-timer works still. All I need to test is the PC sync port (Model Night at camera club should do the trick for that) and find a way to test the meter (darn them for banning mercury!!!) and get some glass to run a test roll (darn all 3 local used camera places I know about for having NO M-42 lenses in stock today) and I should know if I got the steal of the decade or a pretty-but-broken shelf piece.

For those who care. a bit of camera pr0n follows:

Nice catch.
Out of curiousity, could you measure the microscope adapter threads at the mic end for me? Is it about 30mm across with a fine thread? I ask because I suspect a gizmo of mine has a mic thread, but I'm not sure of it.

I love camera pRoN! The Spotmatic series is so beautiful, and then you show this one with its pristine attributes! A REALLY nice piece of machinery!

The first to succeed in persuading microscope manufacturers to use the same threads on their objectives was the Microscopal Society of London, known after 1866 as the Royal Microscopal Society (RMS), which is the origin of the term "society thread," by which the standard is known. The society thread has 36 threads per inch of the 55° Whitworth form. The male thread has an outer diameter of 0.7965 inch (between 0.7952 inch and 0.7982 inch). The female thread, in the nosepiece, has a top-of-thread diameter between 0.8030 inch and 0.8000 inch.
