aerosol spray gun handle ?

[Axle]

I bought a very basic one years ago (probably cost me all of a buck) from a local surplus store, works great. As mentioned, there are a few outlier aerosol cans it won't snap onto, but the tremclad/rustoleum cans not a problem. Makes life a lot easier on the trigger finger. Looking for a photo, but I'm bit shocked at the prices of the ones I am finding.
