Manufacturers’ Codes

The military assigned two-letter codes to identify the sources of aircraft and certain major components, hence a Liberator with a designation of B-24D-NK would quickly indicate its origin as the Nash-Kelvinator plant. Replacement parts would then preferably come from that source rather than other B-24 builders because of possible variations in tooling and assembly methods. This coding system helped in the bookkeeping and inventory departments, as well.
