Pacific Hawk. Designed by Otto Timm. Initially power by two 90 hp Curtiss OX-5. Later changed to 200 hp Hall-Scott L-6.

The following information about this aircraft is from Waldo: Pioneer Aviator by Waldo Dean Waterman and Jack Carpenter
"... a prominent jeweler, A.L. Markwell, propositioned that he would buy the frst twin-engine OX-5-powered plane capable of carrying six people, even with only one engine. We all took a whack at this deal, but I could never get a written contract so I never speculated on it. However, George Stephenson did. He had Otto Timm design and build the airplane, but their "Pacific Hawk" could barely keep aloft on two engines, let alone one.
The typical situation then was noted by an Army Air Service performance report on a new twin engined bomber of 1920 in which it was solemnly set forth as a result of thorough going tests that "the ceiling with one engine has been determined to be 4,000 ft. below sea-level."
Hall-Scott decided that this plane would be a good demonstrator and had me rebuild it, installing Liberty-6's. For the final proving flight Frank Clarke, Lee Scott, E.H. Baxter and myself clambered aboard. We climbed perfectly to 5,000 feet for the altitude test and then went out five or six miles over the ocean, when Frank suddenly discovered that we were almost out of gas. By now we were down to around 1,000 feet and he simply cut off one of the engines and easily flew the plane back to Venice Field, even circling once before coming in for a beautiful landing.
The plane, though, never quite met Markwell's stiff requirements and the project petered out. The last time that I saw it, it was abandoned to one side of Rogers Field, disintegrating, with its engines removed."
