Bob, that's a generous offer. But unless it's something you've made, in which case I'd love to have it, I will simply re-polish, harden and temper the spring that's there. It's likely the frizzen too will need heat treating, whereas the internal springs seem unaffected by the fire. The inside of the lock mortise is not burnt in the least.
I'm still in the process of buffing off the crud and stabilizing the steel. The firemen poured the contents of four tanker trucks into the mess, and their mixture contains something that loves steel. Everyday, the owner brings me more burnt stuff. Today, it's two ball molds for his cannon.
