Highlander,
As much as I would like to give you some answer about it being special it a plant rack of some sort salvaged and pressed into service as a slack bucket holder.
The forge is the gentleman's that got me started and gave me a rivet forge to get me going. I ask him specificly about the bucket holder because it looked like something special i had to have. That top rail just looks useful for something. haha!
Cheers,
Ken
