i have some updates for the scooter. i have a pic of the engine. so.... is it s GS/2 or GS/3 ?

where can i find more infos please... can i find through the frame number the year manufactured?

i am very close to buy a GS 150 but its not as the usual GS 150. i think that its a German model GS4, T4, messerschmitt or something like that. i really dont know the differences. its a vide frame vespa with 10 inch wheels. also the carb is on the cylinder. also the engine cowl secures with something different than a hook system. i started to search to find more info and photos via frame and egine numbers which start with VDS1T and VDS1M (and i found nothing on the net). maybe i could find year manufactured and photos because i think that the vespa i ll buy dont have all the original parts. is missing rear light, horn and maybe a handlebar (i am not sure the one it has it is for this model). can anyone help me or tell me where to search? i am sorry if i am not in the right section. if i am not please move my post to the right one. thanks P.S. i attach a photo i found on the net and seems to be just like this one.
