From the owner, "Yes, it is a Weber & not a knock off. Thanks to all the members who sent information. It was very helpful. I believe it is a 1954/55 model. It has one vent in the bowl (earlier models had just one vent in bowl), it has welded trusses to hold the coal and cooking grates (earlier models the grates just laid in the bowl), there is an axle between the wheels (there was no axle on earlier models). It has a lid hook, top grate is chrome plated and heavy duty. Thumbscrews hold the legs on. The red leg cap and leg show very little wear. Ive been told that "The flatter lid with metal handle, red wheels, thumb screws on leg sockets, long stripped tread on tires, no bottom shelf/tray, I think all date to the 1954/55 model year."
