I don't think you will - they were used with cartridge bearings pressed directly into an unthreaded bottom bracket shell; they had snap ring grooves that had a tendency to break the spindle*. Shouldn't be too hard to have one machined from scratch, but why you'd want to ...
*These were the same bikes that had a cast alloy "death fork" that was held to the steel steerer with a roll pin - that also had a tendency to snap at the obvious stress raiser.
