U.S. Military 27/32-Inch Spark-Plug Wrench with T-Handle, FSN 41-W-3335-40, APCO Mossberg Co.
The U.S. Military 27/32-Inch Spark-Plug Wrench with T-Handle, FSN 41-W-3335-40, APCO Mossberg Co. is a tubular service wrench made for military spark-plug maintenance.
Its internal hex fits the 27/32-inch shell used on 14 mm spark plugs. The removable crossbar passes through the tubular body to form a T-handle for turning the wrench.
Historical Significance
Inspected in November 1951 and packed in February 1952, this packaged wrench is Korean War-era U.S. government stock. Its federal stock number and later NSN record show how a compact service tool remained identifiable across changing military logistics systems.
Military Jeep Tool Context
The later logistics record for NSN 5120-00-230-3696 cross-references Ford GPW-17017-A2. WWII G-503 records list related spark-plug wrenches under Willys and Ford numbers with the 41-W-3335-50 stock-number variant. These references place the offered wrench within the broader military Jeep tool family without making it exclusive to one vehicle model.
What This Item Is and Does
This tool is a single-socket tubular wrench with a removable handle. The hexagonal socket end fits over the spark plug, while the loose crossbar provides leverage through the holes in the wrench body.
