Wander was originally a German company, that also had a branch in Italy. At some time the Italian company became independent, and was subsequently bought up by the Garlatti group. The bike shown by petandbikes is definitely from the Garlatti period. A bike boom bike, nothing more nothing less. I have seen some refined Wander bikes but this is not one of them. This one has gas pipe tubing but the somewhat more refined rear dropout with integrated derailleur hanger. It was almost certainly fitted with Campagnolo Valentino derailleurs originally. BTW, Garlatti also made a reasonably similar bike for Cinelli that was sold in some markets as the Riviera model.
