I bought a Gold Crown 1 and the slate is cracked up badly. Local table mechanic could not repair with wax due to severity of cracks. I need the middle piece of slate but will buy the whole set if I need to. Thanks for reading.
You could contact this guy, he isn’t too close to you (Maryland) so shipping might not be an option but he carries replacement parts for gold crowns. I have bought gold crown parts from him before and everything was as described, I don’t see slate on the site but couldn’t hurt to ask. good luck!
