Dan & I picked this up years ago as well. When we purchased it for a song at an Antique Market, god knows where, it was all dirty and rusty. It had been used by Farmers to transport chicks from farm to market. There would have been lots of these in a truck or wagon carrying chicks.
We sanded it and refinished it, then painted the wee wires black and now it's a conversation piece, as well as a tidy place to put our many different pepper shakers, salts and gourmet oils.
