Find a donor bike. I picked up a bike that had Ukiah rims that are 27 - 1 1/8. FWIW, they were on a touring bike! I swapped them with another bike that had 27 1/4 rims of similar vintage.
If you have the patience, you can find a bike, swap the wheels, then resell the bike. Buy right and you should make a little on the swap.
