Nice! If you come across a Frontierland Outdoor Foods (Westward Ho, Turkey Wagon) costume, I don't want it. Nothing like brown pants and long-sleeved, brown flannel shirt in the summer, in Florida.
Costume is from a former Disneyland cast member. I believe it's dated from around 2000-2004. I've scoured the web looking for something similar that sold or was for sale and haven't found it yet.
I worked Jungle in 2005, and we were still wearing the khaki pants and tan shirts, basically the same outfits as they wear at Indy. I think these came in a couple years after, so that one is more like '06-'07
