I recently acquired a moped from my step grandfather who got it from a friend of his. His bud knows nothing about it, but didn't want it hanging around his basement anymore. I got it running pretty much as good as it can get. I have determined a few things. It is a 1978 model, it has a TAS sticker on the engine, and a Lambretta logo on the seat. Other than that I can not seem to find any markings. It is canary yellow and does not look to be repainted. Know a good place to look to exact ally determine the make and model of this moped. Any help would be greatly appreciated.
