68/73mm shell, which size axle is needed? Not bottom bracket but crank.

I'm trying to buy a crank for a short person, me, 165mm crank arms.
Sellers do not know what shell they fit or what bike they are from so they have measured the axles they are between 130 and 135mm long.

I'm guessing that is 68/73 rather than boost. Can you even get a boost crank in a 24mm diameter?
