Those are the same replicas found in Weber Grill Restaurants and they were used as store displays in some cases. Super cool that you got ahold of one of these! I’d cook on it! But that’s me... as lightningboldtz mentioned, yes they did “cheat” and use a modern lid vent and three modern large dual tab daisy wheels, the original only hand one lid vent and one bowl vent and both had a small welded on square tab. Congratulations!
