I am looking for the key, #18 on the parts list for my SBL 13, of you have one please let me know. And I am also looking for advice on how to remove the old one. Finally found the set screw holding the key, it was buried underneath layers of paint. Removed the set screw, and tried desperately to grab the key with a bent needle nose pliers it would not budge. It must stuck in there good, or there is a known trick on how to get it out.
