This is a strange one. It has the body of a GS160 mark II, but has a different headset, and the forks off a Vespa Sprint. The 1961 to 1964 models have round headlights similar to a Vespa VBB. The 1965 model has a trapeziodal headlight. If anyone has more informtaion please email me. Click the images above for larger views. Thanks to Wayne for the pictures & Angel Lede for the info.
