Left Hand Paragon
c. 1916
Markings:

SC 6711
P140
8'8" x 7.75'
Left Hand
Comments:  This is believed to be a very early Paragon Propeller, although its exact application is unknown.  The "SC", or Signal Corps, suffix is a very low number, suggesting that it was issued very early in that process.  The left hand thread is unusual, as is the six bolt hole hub.  Further research would be needed to accurately identify.  The Baltimore location dates it after 1912, but the low Signal Corps number suggests a manufacture date between 1914 and 1918.

Wood:  Oak
