Ahhh,... Lightbulb moment = I had not checked the Olympian spec for crankset, ....or forgot I did, ....or did not put 2+2 together. Purchased the AD Olympian from a flipper (15+years ago) who had several frames and many cranks, etc. Given 170mm length, it may not be original to the 62cm frame, or that was my thinking. Maybe the BB is also original, too. Doesn't matter to me, this one has been a keeper.
