There is a welch plug on the front of the neck you have to remove to get the plunger out. But why remove it?Be sure to visit;

1948 Frame Lock
Has anyone ever removed a lock intact? The lock in my 48 frame is frozen, not sure if it is the plunger, lock or both. I really would like to remove it intact if possible for repair, again if possible, rather than just destroy it and replace it with an incorrect for the year lock from Bill's. Were the earlier wishbone locks held in with a screw or a rollpin? The visble head on mine looks to have a slot in it or was it staked in place? I had a key made for the lock, cut from code but it will not budge. The frame is a real cherry and I hate like hell to drill the lock out. Any ideas?? Thanks, John

Hack!
I have removed several cores intact, sent them to a locksmith for cleaning and a key, and then re-installed with no problem.
I do not know when the rollpin was introduced, but most earlier models will still have a nub of a screw where the head had been chisled off after installation.
A 3/32" left-hand drillbit will occasionally draw the old screw out with it.
The critical aspect is to avoid drilling too far, into the core.
Feeling with a key, even a wrong one, gives leverage to loosen it.
I preferred to re-pin the core by tapping for a setscrew, and capping over it with paint.
I also avoided re-installing the spring, as that would seem to be a liability if the tang ever broke away from the back of the core, for it could suddenly push the rod forward, and lock you up in a turn!
Good luck,

My 49-50, or possibly it's a 51 Wishbone had a solid pin. It's been 20 or so years ago but with an hour of drilling-checking and drilling I was able to drill thru the pin and the tumbler came ouy pretty easy. Never thought about tapping and using a screw. Could of used a short screw, filled the hole with grease and capped it with a short plug.
