For me, it would be OM-2(n) or OM-4(T(i))
The OM-1 requires a 1.35v battery, which haven't been made for decades, or a 
special adapter for a 1.5v battery, which is good, but not perfect. Just too 
much hassle, when an OM-2(n) may be used fully manual, if desired.

My favorite is the OM-4 body. Many plain OM-4 bodies have the later circuit installed. For 
practical use, those, a "T" or a 'Ti" are all the same. Better auto exposure, 
both spot and ESP, than an OM-2.

If the user gets interested in TTL flash, the 2n is better. If they start using 
a tripod, the bodies before the 4 series (and OM2000) have no way to control 
vibrations from the aperture stop-down mechanism. Self timer on the 4 series 
pre-fires mirror and aperture as soon as the shutter release is pressed. The 
extra wait is a pain, the results, especially with med-tele and longer lenses 
and light and/or metal tripods, much better.

My latest loaner for a student was an E-M5 II. 😁

Unfortunately my OM-4 (sn 1,058524) draws the dreaded 400-600uA, while in M60/B 
it draws around 20uA. My OM-4T draws about 5uA.

Serial number means little. They may, or may not, have started putting new circuits in late ones, but I've never seen numbers. It seems Oly replaced circuits in a LOT of OM-4 bodies, because of exactly this drain problem. It was easy to test, and back when, sellers often noted new circuits.

I had three plain OM-4 bodies, all with the new circuit. One went to Chuck, one has a slipped second curtain and one, last I checked, was fine. I also have a 4Ti in almost new condition and in brown leather case. Kinda silly, as I doubt Ill ever actually shoot film with them.

What if the Hokey Pokey *IS* what it's all about?
