A mate found ( in a skip ! ) a Redline F+F . It is as follows ( no pics yet I'm afraid ) .
Chrome
4" headtube
Redline oval stamp on BB with - DSBM 40110833 .
Forks like MX/500A/600A with dropout plates fixed to front of fork legs , plates angled up slightly at ends & they don't go lower than the fork length/bottom .
I'm guessing 500A or 600A , maybe MXII/III but not many of these around in chrome .
Any thoughts ? .
