I found it interesting that my late 1970s Rauler was built to accept 27" wheels vs. 700C. Just goes to show that you can't use a general wheel size rule for higher quality Italian, European, or English built frames/bikes from the 70s.
Here's the Wool Jersey address to view photos of my Rauler complete with 27" wheels (Campy Record small flange hubs laced to Weimmann 27" concave rims):

Speaking of 27" wheels, I am about to build a pair of correctly sized 27" wheels for my 1949 Hetchins Super Special, since that's what it originally had mounted and the frame was built to accept.
