I probably have, I'm getting old and shoot from the mouth sometimes. But I do stay narrowly inside my interest area.
It may actually be why the idea popped into my head, I'd seen it before. So the concept came, but having seen it did not.

I do observe they take a lot of verticle (or wide) space. Works for trains it seems!

The "Comma Knocker" was very popular in trucks in UK, Australia and New Zealand, especially milk trucks.

The nickname came from the very loud mechanicals noises they made, very interesting engine ..
