And what kind of gadget is this? Looks like a small cement mixer.

Interesting subject. I have no idea what it is but I think it works.

...it does appear to be an old cement mixer, but well presented here. Thanks for sharing.

What I like most about your picture is the combination of textures and colors. From the beveled glass behind the mixer, to the spattered walls. I like the variety of shapes too. It's nice that you could see something artful in the mundane. Good composition!
