A number of propellers were built in the mid forties under military contracts using the year of contract as the first two digits of the design number. These military contract propellers and their common Sensenich number designations are cross referenced below.

Several wooden propeller manufacturers built props for the same aircraft under the same contract number as Sensenich. In order to find the aircraft using any prop using these military design numbers, locate the equivalent Sensenich number on the Sensenich page and you'll find your aircraft.
