Edit: I live in San Diego, I could always bring it into the shop.
The Sprite is a tough one because the BB threads are 26tpi, which is specific to old Raleighs and not compatible with modern English-threaded BBs.
Aside from Phil Wood (which may be more than you want to spend on a conversion), I'm not sure of anyone else making a replacement BB with that threading. If the cups/bearing races themselves are in decent shape, you could always just replace the spindle with whatever length you need for your new crankset.
