No, I haven't had any luck with my post on the bikeforum site. The experts I have spoken to either by email or phone just don't have any information. Without a serial number, they are stumped and there is not a serial number on the bike. Just seems to be a bit of a mystery.
I contacted Raleigh in the US and the Customer Service person wasn't able to help me. I did send him all my photos and he said he would ask around for me.
The bike was given to me and we don't have any use for the bike so I am thinking of putting it on Ebay as is and see what happens.
As for the link you posted, those are all 3 speed bikes and mine is a 10 speed. That is where most of the confusion regarding the bike comes from.
