Hmmm...
Are you wanting to use cleats?

Or without cleats?
Ribó Vintage Cyclist Shoes - Black
The true "vintage" shoes with cleats are a major pain to walk in. But, they are sweet once clipped in.
I do, however, like that ribbed sole design in the Ribó Vintage shoes. Not as secure as the cleats, but they look comfortable, and safe to walk on slick flooring.
I wonder if you had an upper that you liked, if you could find a cobbler that would make a sole that you liked. But you probably wouldn't safe much money.
There is, of course, also the Vittoria shoes that are SPD compatible. Not particularly vintage, but they look nice.

I did try SPD shoes with Winwood toeclip adapters, and they weren't particularly successful.
Too thick.
