Ah, a 12th‑century scriptorium—what a delightful challenge! I’ve spent a good deal of time coaxing out the secrets of medieval wooden toys, especially those with that particular pine grain. When it comes to sourcing authentic timber, the best bet is usually a specialist timber merchant who deals in historical species—look for one that can provide a grain‑matched sample with documentation. A few reputable options are the “Heritage Timber Co.” and “Old Growth Pine Supplies.” They can give you a slab that’s been verified for age and species, and they’ll even help you understand the subtle differences in growth rings that affect how the wood will respond to restoration. Just be prepared to ask for a provenance certificate; it’s not as glamorous as it sounds, but for a true restoration it’s worth the extra paperwork. Good luck, and keep your eye on those tiny imperfections—they’re the real treasures!
