Frame is stamped 73 and rear deraullier 2/72,so it is a good match according to what I have found.Frame is close to 22".I'm almost 5'9" and it fits me perfectly.Here are the component name brands on it;Simplex derraulliers,Mervar star crank,Mavic wheels,Balilla brakes,Suntour shifters,Belleri handle bars,Brooks saddle,Atax handlebar post,Simplex wheels quick release.Frame is made of "Super Vitus 971" alloy.All in all a complete vintage bike in original condition.Has scratches here and there.Its my opinion that it should be left as it is.Send me your e-address and I'll send you all pics I have........thanks,Albert
