Anyone Seen A Style Like This For Big Men?

I was out with family at a play and one the gentleman greeting us at the door had exactly the sort of woolen overcoat I'm looking for. Has anyone seen a coat like this in really big sizes? I generally take about between a 62 and 64 Tall.

It could be longer (I go through Minnesota winters so I want my overcoats to be ankle-length if possible to cut down on the impact of cold winds against my legs), but the style, here, is the sort of thing I'm looking for.

I asked the man about the uniform and he didn't know where it came from. I hit iTailer.com but while they have a few features similar to these, they don't handle my size by about 4 inches across the waist and chest.
