I finally found the Mahasarakham University Museum. As far as I have been able to determine, for some reason, this location has not appeared in any travel blog, or blog or TAT. It is a good stop for a number of reasons; 1st it is interesting and 2d it is never closed. Signs describing the buildings are both in Thai and English. If you are interested in traditional Isaan housing types the place is worth a couple hour visit. The small animal park is a small bonus.
