Thank you. This is the end of the barrel from a cement truck. It is the end where the cement would pour out. I've found a storage lot where there's probably about a dozen of these at any given time. I'm not really sure exactly how many rolls of various speeds of film I've shot there, but it's quite a few. As I print more from that area, I'll definitely post them here. Actually, my image "Teeth of the Machine" is also from a mixer barrel. It's the gearing used to turn the barrel on the truck.
