These are quite common with European truckers

Its kind of like the swans that the old timers started putting on their radiator caps back in the 1950’s for a symbol of good luck and beauty. The tradition still carrys on today. That is why Peterbilt adopted the swan bird wings as the grab/pull handles in 1965 with the first tilt hood 358’s.

 

I remember a guy who used to run an old decommissioned Schneider cabover in the 90’s that had one of those. He ran between St.Paul and Chicago and I’d see him every week. I also wondered what it was all about. I remember his handle used to be The Great Pumpkin. Lol.

 

I thought hanging your polish or Russian car license plate on your Volvo was the cool club badge in Chicagoland?
