As some of you ol' timers may remember, I found a couple of those at work, in an attic, on a home inspection a few years ago.
I was able to make off with a pickup bed full of basket case for $500.
We spent a few weeks attempting to make sense of and assemble a bike out of the frames, tanks, and boxes of cases, cyls, carbs, etc, etc, and finally gave up when we didnt have a front axle and couldn't find one off a road bike that cross referenced.
We ended up selling everything for $5000.
Yup, Mark, that's Patrick of the Broken Bone patches and the "Not afraid to seize" and "port map" T-shirts.
