Metal push bars

So I’ve been researching dates and manufacturers of these push bars. I see that one of my Coca Cola bars was made by P&M in 1952 . The other one is only 31” long shorter by half an inch . The stamping in muddled, I can’t tell name of manufacturer and it looks like 1947 ? Is that possible? Anyone have one or run across a similar item?
I’ll post pictures of two 26” tall frosted glass coke bottles ... when I get to back of storage. I haven’t found any info on them yet. Thanks
