Help w/ID Western Flyer

[CYMBERT]

I recently started cleaning up a Western Flyer that I picked up a while back. I found what I believe to be the serial number but not able to find a place to look it up. Any help would be much appreciated. The numbers were stamped on the head tube.

So far by the MO that it is a Murray built Western Flyer but we will need at least a picture to help out for the years it might be unless one of the guys here know something.


Also since it is on the headtube it may be 70's & 80's possibly but I guess the other.
