Neil, like Revdocdrew said, the FW (Featherweight) are different from a Regular grade. On the FW there are three screws that hold the side lock on. On a Regular frame there is only one screw that holds them on. The only thing you can do is find out which type you have and see if it matches up with yours in size and then try it into the fit. Best thing to do is put them back to back and and see if they are the same size.
