Actually, the Victor Home Recordings discs are straight up modern vinyl in every perceivable way -- exactly as flexible and plasticky as today's records. And those were what, 1929? Vitrolac, MGM's Metrolite, and other branded fomulations were part vinyl, part shellac-type something-or-other, and were certainly more flexible (less breakable) than shellac discs, but they were still more like shellac than pure vinyl. Meanwhile, the V-Discs from WWII (many of them but not all) were fully PVC like modern records. Vinyl didn't become common until the LP in 1949 as far as I remember.
