Bought this frame and it has never been assembled before. It was found in a backroom of an old Schwinn shop in Arizona. All I got was the frame no forks, neck, handlebars or anything just the plain jane frame with bb cups and headtube cups. I bought everything else new. It' s a 82-83 national but I'm not sure of the model? It looks a lot like my Stratton but the back dropout are different. So if anyone has any info on it please feel free to comment. I know it was made in Tiawan for a company called BITD the UK other than that it's all I know.
