May I offer another resource? Kremer pigments deals in some rare stuff used by pro classical oil painters, artists, and conservators. Including stuff for re-finishing rare musical instruments etc. They do carry some of the toxic old-school chemicals for some things -- so you might have to sign a waiver and insurance. VERY traditional stuff. Link: https://shop.kremerpigments.com/us/
