    Shimano 7410 on a 103mm BB: I was hoping for <140mm.

    Back to the drawing board...

    Yes, you need 7400, not 7410. 7400 was designed for a 112mm axle (conventional BB, flat faced cups), 7410 for a 103mm axle (cartridge BB, rebated cups), so it's only the combination of 7400 cranks with a short axle which gets you the low Q

    If you're happy with square taper, Campag Pista is supposed to be 131mm, nice but a bit pricey. Omnomnoms are 135mm for half the price.
