Just a heads up to anyone who might be looking for something like this. I was at a building salvage yard over the weekend in San Francisco and saw this sitting on the floor over in the enclosed interior parts shed. No idea of condition or price (the guys that run the place like to haggle all the prices) I am attaching a picture.
The place's website with directions is: http://www.buildingresources.org/

Nice 12" set; maybe a KV-1215. If it's in clean physical shape, and in working condition, it's worth grabbing in the $25 range. Beat-up, it should be left there.
