Some used OM-4 bodies for sale are disguised as OM-4 Ti.

As I understand it, Olympus offered board replacements for the affected cameras back in the day. Apparently Olympus didn't get all the affected cameras!
BTW, the quick check to see if you have the updated board is by putting it on battery check and it will beep/led light for 30 seconds and stop. If it doesn't stop then it's the old board. Both my OM3 and OM4 stops at 30 seconds.
