A while ago I bought a pair of Hi-E hubs at a swap meet. The interesting thing about them was that the front was a 32 hole while the rear was in a high/low configuration.
The spacing on this rear hub is 121mm accepting only a five speed freewheel. The drive side flange is 69.5mm with a spoke count of 28 and the non drive side flange is 46.5mm with a spoke count of 14. This would give you a 42 hole wheel.
I tracked down the Hi-E crew 10+ years ago when they were still in business located I think in Tennessee. They indicated then that they were still building hubs and rims for public consumption. I'm not sure if they are still in business or not.
