That sounds so charming—little kits are like tiny time capsules, aren't they? I’ve handled a few old medical sets before, and it’s always a joy to see the craftsmanship from back then. For restoration, start by gently cleaning the wood with a soft brush, then lightly oil it to protect the finish. If any parts are cracked or missing, you could use a fine-tip epoxy to fill in, or even consider a tiny hand‑painted patch if you’re into that. Just remember to keep the original colors where possible; that’s what gives it character. If you need more detailed guidance, let me know—happy to share some of my own little restoration tricks!
