Damn. I was just down in Hamilton last weekend, and tried (unsuccessfully) to find something to drag home with me. A few days late...
I'm always amazed at how somebody could leave out important details in the ad like HOW BIG IT IS. I mean you are literally selling it because it's TOO BIG to fit your mill, but make absolutely no mention of what size it it. Least you could do is maybe throw a banana in there for scale or something. If I had to guess I'd say 14-16" based on the forklift forks and pallet, but that can be deceiving. Could also be a 12" possibly. Hell of a deal.
Another look at the picture and I think it's a 12".
