I've been told by some that the counterweight in this picture may have come off of a crane or some other large piece of construction equipment. I'm curious if anyone recognizes it and knows what it came off of? I had 13 of these that average 1140 lbs. a piece. They're stackable and have holes to bolt them together. I'm wanting to sell and replace with lead weights, but can't find any info out on these. Thanks for any help.
