I have a Brahmin of Burden, but that's not what I wanted in this case.
I decided to go with this for the doctor (a modification of Pixote's rip of FOT graphics):
It's a little small on the map, but that's for the best I think (it gives the proper impression of what's going on, without being in the way).
The doctor also sells some patent medicine. Here's the item graphic for that (Model from sharecg, credit to Jim Farris).
I could see that turned into a Tecate courtyard-house style building.I think it fits in perfectly Ursa.
Some unfinished not sure if usable stuff on the right you see the original.
