This entire site was started as the result of my finding a Redline with no decals. Having only the style of bike to determine the model and the serial number. I could figure out the general model easy enough with a little digging. It is an MX-III. But what year and was it a 500a or a 600b or originally sold as just a MX-III frameset?
This got me to start a thread in BMX Museum. It was stickied by the staff at that site. It is always a work in progress. You can find the thread here: http://www.bmxmuseum.com/forums/viewtopic.php?pid=212431#p212431
Sorry I cant figure out how to make it a clickable link.
