Identifying this Redline?
 

I picked this bike up on the cheap last week and I am trying to figure out what year and model it is. Some of the parts might need to be replaced and I am trying to figure out if it is worth enough to put the labor into it.
The serial number is RMCF901621 and it has PRO stamped just below that.
I tried to find it online, but I couldn't find anything. The bike doesn't seem that old. Sorry for the crappy picture too. I am not at home or I would take better ones before asking.
Thanks for the help

It doesn't look that old, so you might save time by jumping to the last page and working your way through backwards, since they start in 1974
