The AW hub is one of the ones that, in the rare event something does break, I'm pretty confident I can replace the part with a good one. There aren't too many other vintage hubs I can say that for. Perhaps the New Departure Model D, but AW parts are still common as dirt. Hopefully that will never change.

(the notable exception is if you need a shell with a specific number of drillings that aren't 32 or 40)

I've dealt with my share of 3 speeds, none had NIGs-- the vintage stuff seems to be what crops up here in the US.
