I am still researching my Cherubim. I am not finding any frame numbers or ser #. Where should I be looking? This was a custom made bike for a Marine stationed in Japan probably 70's. I am out of touch with him so I can not be sure. Is there a way to date the bike using the equipment? It is all original except pedals and seat. Is there a shop in So Cal, close to Temecula, that would know vintage bikes and how to find clues as to age? Would it help if I take photos of all markings and show photos here. I have written Andrew Muzi but have not heard from him yet. And if I have not asked enough questions yet let me ask one more. I need 1700 for new bikes ..am I dreaming of finding it in this bike. Thanks, Thomas
