1933 Stinson Model O reproduction.

From EAA website:

The Model O was originally designed by Robert Hall (of Gee Bee fame) as a military trainer and was configured for aerial machine gunning and bombing. A total of 10 were made in 1933 and 1934, five of which were sold to Honduras, three to China, and one to Brazil. The prototype stayed in the U.S. and ended up as an instrument trainer in Long Beach, California. It then was moved to Love Field in Texas at the start of WWII, and fell off the CAA registry in 1945.
