vintage coal insert

We burn hard coal in a Hitzer F82 furnace. My husband is building a fireplace in the kitchen and wanted to use coal so we were looking for a coal basket. We came across an insert that has "up to date" stamped on the back plate of the burning basket. I found one mention from 2008 about the same phrase on an insert. I can't find anything any where on the internet that mentions that phrase. It's a hard phrase to search. The price is good considering what I have read about how rare they are. I want to make sure it's all there or at least know what might need to be fabricated. It looks to be almost completely intact. I need to know more about this particular one. I did PM the member from 2008 but no luck.
