I have seen one of these myself in April of 2018 at a hardware store within walking distance of Weber's factory in Palatine.
If I remember correctly the bowl was smokey joe size with leg sockets welded to it.
I tried to purchase it but the lady that owned the store said it was her fathers and did not want to part with it.
I gave her my number and told her if she ever wanted to let it go to call me.
I believe I may have even posted a few pictures here about it.
