Raleigh has made an R100 model from mid 90s till recently, as here:
Look for any stickers indicating the tubing used (e.g. chromoly double butted / Hi-Tensile) someone will have an opinion on whether it is worth it / not. If it has semi-horizontal dropouts then its an older frame. If it has vertical dropouts OR dropout spacing 130+mm then it is newer (and may not be fixable but I guess thats not the case?!)
If the frame fits you + is fixable, no reason not to use it, especially if the frame was cheep.
