Unico - Liberty Engine
c. 1918
Markings:

None
Comments:  Although the Unit Construction Company was a large producer of wooden propellers in the teens, very little is known about the company.  This propeller was made for use on a Liberty 450 HP engine, but the aircraft use is not designated.  The absence of metal sheathing suggests that it was more likely destined for a land based plane such as the DH4 than one of the Navy flying boats, which more typically had metal sheathing to protect the tips.  Note the fabric visible beneath the decals and the sideways placement of the decals.

Wood:  Mahogany  
Length:  9 feet, 6 inches
