Those 219s were a beautiful piece of work. I had a 219L that L stands for side lever, and it was nice, but not near a s clean lines as the earlier 219.
I gave that .22 Hornet to a grandson 8-10 years ago.
Those guns do have a reputation for occasionally using an extra firing pin, but if you have the pieces to the old one, a good smith should be able to turn out a duplicate, and harden/temper it.
