1977 Redline Proline

First Year Redline Proline

 After doing a lot of research, this is the oldest Proline I have found anywhere. 4 digit serial # 5851 PL dates to 1977 Proline's.  Redline frames with 5000 series serial numbers were made in 1977 that includes MXII'S. This is frame set is made even more rare because  it has the small gussets connecting the down tube and the head tube, these gussets were not used on the very first 1977 Proline's but after problems with the frames cracking in that area they began using these gusset on the rest of the frames made in 1977 and into the 1990's
