yes, there was one for sale in arizona last month. somebody posted link here. ggogle "images" is your friend!
just wasn't sure if he knew what he was talking about... http://sfbay.craigslist.org/eby/cto/1447484354.html
There were kinda TWO...Model 68B had vertical windshield and lots of wood structure, sold '30-31, and Model 68C with modern steel structure and slanted posts was later '31 only. 68A was the designation for '28-9 type.
The later 31 slant window I feel looks the best. The problem is the wood structure in the flooring ,were most are rotted away or dry rotted. There is a old 1970's rod in our area,its rough but cool. Kinda like the 32 cabriolet but not big production numbers. I would think the Ladies would like the option of Roll-up -windows and Top I know my wife loves the option and can be used to do chores, our 32 cabriolet doing some grocery hot pepper shopping
