1959 Coca-Cola Push Bar

A fellow collector who does mostly general store type signs recently got delivery of this push bar.
I wanted to help him confirm if authentic. At only 24 3/4" long, it is shorter than the one I have. The trade mark stamp goes outside the tail of the C, and is the manufacturers stamp from an actual manufacturer?
I think I heard something about different sizes, but wanted to be sure due to the price he paid.
He said it feels like the real thing and the weight is substantial, typical of the style.
Any help is appreciated.
