Some time ago I acquired a 1959 Parker 51 fountain pen that came with a matching mechanical pencil. The pencil works fine. By pressing the rear end I can move a pencil down and keep writing. The spring action seems to be OK. However I can't seem to open up this pencil at the rear. Which part is supposed to be detachable in order to re-fill the compartment with pencil sticks? Everything is super-tight and I don't want to damage anything.
Thanks!
