Brand Identification.
 

Hello. My friend brought up an older road bike, with huretparts. And this symbol. If you need pics of the bike, however it has been repainted, let me know.

My best guess is the bike is from the late 70's early 80's. Here is the symbol that is also marked on the frame in a couple of locations.

Though I've never seen the logo quite like that, it appears a Motobecane or a Motobecane manufactured brand, such as Astra.

Motobecane plugs on a..... huffy? schwinn? motobecane? I thought Piaggio made Astra?
