Can't say exactly, but as they don't have the weighted secondary flappers, I'd say they're early GM, like 53-54 Buick, 55 Pontiac or similiar. the later 50s Chevy and mopar WCFBs had weighted secondary ****erflys. Chevys had straight arms and Mopar curved. Chryslers had va***n secondaries from about 57 on, maybe a bit earlier. Do an ebay WCFB search and you'll see some to compare. Good luck.
