Mike,
That wasn't "just another CA Masi" in that this ine was built by Mario after hours for someone in particular. It's Columbus tubing. Numbered "M4". I've seen two others numbered simularly, and they were for "special" friends of Marios'. Thus, the milled dropouts.
Off to the San Diego Vintage Ride!

Hopefully we'll see it at Le Cirque next year.
