That's great, what a beautiful bike. What size tires will fit on that?

I found the MAP from the ebay auction,
Here is the album: https://www.flickr.com/photos/776465...h/15352672369/
here's the rear brake, I would say there could have been more clearance if it had been desired. Those look like 25mm tires to me.
