It wouldn't be a Jingles Man Cave (or is that Gnome Cave?) unless there was a tank in there somewhere. This is the Forces of Valor 1:16 scale diecast M4A3 Sherman model, produced in a limited run of 2500 models, and I've got one.
I got mine from Buy-For-Less-Online via Amazon UK for £155.67. However, this was a sort of bad news / good news situation, as you're going to see.
Bonus content at the end of the video as usual, showing some more World War II themed "toys" I already own.
Current total cost of Man Cave decorations £1272.13, or 6,716 days of premium account in World of Tanks.
