52cm Rene
Herse on eBay in Iowa for a pretty low price, $2100 plus free shipping.
Cons: Period incorrect repaint. No derailleurs or original racks.
Pros: The repaint looks like a decent one, even if not faithful to a '1945' Herse. It comes with Herse cantilevers, stem, and cable hangers.
I'm tempted as it's probably the lowest price I'll ever see for a Herse, but I don't like that it's a repaint.
