WTD: Shimano compatible external BB cranks

[letmetalktomark]

Was planning on using some trusty Middleburns for my next build but have a wonderfully tasty external BB that is begging to be used so am on the lookout for a set of Shimano cranks.

Need to be Shimano ideally and wouldn't need rings or BB etc.

Would however need to be 175mm long.

WHY?
