Well................ Obviously the outside could be as small as a 46T, as that is the smallest possible. But that would be a "Polish Team" arrangement (apologies to my wonderful Polish friends who thank God have a good sense of humor. See the rear cog here:

Inner and outer chain rings are the same animal, just flipped around. So ANY 151 chain ring will work either position.

I hate to add this, but a 45 tooth any-brand or a 44T any-brand simple won't go on these cranks, for the same reason the beat-to-death "39 tooth Super Record" chain rings for sale on eBay not so long ago!

<< And was there a specific chainring designed for track cranks that differs from their road chainrings? >>

Only that the Track rings are wider toothed at 1/2 x 1/8" rather than the road which are 1/2 x 3/32" . And of course there are 1" pitch track chain rings with half of the teeth......They all fit the same crank arm dimensions..
