Did you buy a well painted Baneblade at Historicon?
This is a long shot but it doesn't hurt to ask.
I bought a bunch of W40k Imperial Guard stuff from a guy at the Historicon flea market this past weekend. One of the items was a sentinel as shown in the pics below. The wonderful guy who sold it to me also wanted to give me the driver and cage but realized it was accidentally in the box/bag he gave to another person who bought his Baneblade painted in a similar style and color scheme.
The Sentinel as I bought it:
The missing driver and cage for the Sentinel. Missing is just the driver and cage shown here.
Here is the Baneblade the other fellow purchased. Look familiar? Hope so!! :)
If you happen to be the guy who bought this Baneblade at Historicon, and if you happen to have the driver and cage for the Sentinel in your mix of stuff, could you contact me here or via PM or offline?

Also a long shot, but if you bought any of this guys other stuff (a few other tanks and APCs) I'd be interested in hearing from you as well.
Thanks for reading!
