Removing SMLE Fore-end Rear Screw Wire

[muffett.2008]

Sure seems that you are making a big production over a simple task.
The rear crosswire used to strengthen the draws area, can be removed by simply cutting out the small centre section of wood(if not already broken out) and using a pair of long nosed pliers, unscrew the wire until it protrudes from one side....then complete the unscrewing from the side.

If done carefully enough, the wire should be good enough to reuse.
