Sturmey-Archer internals interchangeability?
I've been given a bike with a badly busted S-A AW 3-speed. The axle has broken and the left half is missing entirely. Doing a rough calculation it seems like I'd be able to buy a used hub from Ebay for about the same or less money than what the spare parts alone would cost me.
Question is, which ones can I use?
The bike is only a few years old, while the Ebay hubs are tagged as being vintage. Spoke counts doesn't match, so transplanting the internals is probably the only option.
Can I use "any" AW hub, or is it a particular year that I have to match?
