If there is a local bike co-op (or similar) check there for used hubs. The one I volunteer at literally is awash in used hubs (yes we have buckets if 'em) as many wheels come in with bad rims so we cut out the spokes and save the hubs. (Note: all the scrap metal goes to a recycler so there's no waste) If you do decide to buy a used hub you will want to check the ball bearing size. Almost everything of that era used the same size balls but there's always that one...
Another option is to go to a thrift store and buy an old 15mm wrench and cut the handle down so it'll fit in your saddle bag. Wheels with bolts seldom get stolen, I can't say the same for quick release wheels.
There are many "standards" for axle threads so if you want to reuse the original cones be sure to bring the originals to make sure you get the appropriate axle thread.
