You need to go for the books unless you have access to a library with a strong historic music collection.
Some book titles that may help.
Baby Dodds Story
Drummin Men (covers early jazz players, may include Morehouse, I don't recall.)
ReBeats sells drumming books: http://www.rebeats.com/books.html
Since Morehouse was a Leedy endorser, you could look for Leedy catalogs. some stuff right here including a pic of Morehouse behind what looks like a 24" kick: http://www.vintagedrumguide.com/reference_catalogs.html
Also, you could search Google Book, and see if you can find any useful chapters in books for Morehouse or the Wolverines.
