I couldn’t resist that one, when I was learn to be a mechanic, the first shop I worked and made me call up the parts store and order a valve cover return spray, and then they asked me if I want to muffler bearings to go with that!
Anyway to be honest it looks like something from a Drum brake setup. But being it in your ashtray I would go with something mechanical in/on your dash that has a spring attached to it for return a position.
In my very first RV, underneath the Cabover bunk mattress was a strange looking, powder coated, Z bent bar, about 24 inches long. I asked everyone at the dealership and in the shop, no one knew what it was for. And one day I saw it on my slide while it was in. It was actually a lock mechanism that stopped my slide from sliding all the way out! Yup, it was missing from the other side! So you never know what they’re going to leave out these days! And that was in 2016!
