I have 3 bikes that came through my Garage in the last 12 months where the adds were cryptic at best with photo's you needed to examine to find out if there was something good.
I bought a Gitane (listed as an "Old Italian Bike") since I saw a NR Triple on it. It was full campy and the frame found a good home with Goucho777.
I bought a Carlton when I saw it had some Campy parts in a pictures, but it was the NDS picture that showed a long cage (not sure which) that got me to drive over to pick up the bike for a 1st Gen Rally (and all the other parts).
The last one was an odd Pugeout. I saw High Flange Record rims in the picture and a price of $40. I was in the car within 10 minutes. It was all lower-end, except for the hubs, Campy pedals, and Ideale saddle.
My Eroica Bike has the NR Triple, the Rally, and the Ideale saddle from these purchases.
