Hi, I found this Puch Super Cavalier at Goodwill. I've found some info on the Cavalier, but thats not this model. it rides & shifts great, so I'm going to change out the handle bars & saddle. Refurbish it over the winter and ride in the spring. Anyone familiar with this model & idea of year made? What about Puch Bikes in general? Suggestions on removing the surface rust & touching up the paint? Here are the specs & pics: Seieal # 5589743, RD- Suntour V-Luxe, FD- Compe-V, Hub- Normandy 05076 France, Cluster -Regina Italy, Crank SR Apex, Rims-Rigida Chrolux Superiur, Brake center pull Weinmann 750, Puch Special 482 tubing, Made in Austria
