Original Item. One-of-a-Kind. This is a very interesting fuze for an American torpedo made into a cutaway for training purposes. This is the first example of a WWII Torpedo fuze we have offered, let alone a cutaway. It still retains marking along the brim for manufacture by Y.S.&L. Co. and a manufacture date of 7-1941.

Unloaded or dummy grenades, artillery shell casings, and similar devices, which are cut or drilled in an BATF-approved manner so that they cannot be used as ammunition components for destructive devices, are NOT considered NFA weapons. This example is in total compliance and is totally inert. NOT AVAILABLE FOR EXPORT.

When it comes to designing a training program for military personnel, instructors are faced with several challenges. First, unlike athletes there is no off-season, most units are either preparing for deployment, deployed, or refitting from deployment. Secondly, training facilities vary from location to location and often focus on a single task. These tasks may include muscular strength, cardiovascular endurance, field craft or marksmanship. Each of the above contribute to the success of an operation, however there is one area of training that is deficient. This deficiency is visual training; visual ability plays a larger role in achieving optimum performance than most military personnel realize. The goal of integrating visual training into an already packed curriculum is not to dilute it but to improve tactical performance.

To help users better understand the equipment they are using, examples like this cutaway were made. These were intended to give the users a look at the internal structure of the explosives, showing the different layers as well as where they connect or thread into each other.

The fuze measures roughly 13½” tall with an exterior shell made entirely of brass. The cutaway shows the internal mechanisms and components of the fuze, which is actually very intriguing for a torpedo fuze. The end of the fuze is missing some threading as shown. There are likely markings missing from the rim due to the cutaway, but the markings that remain read: 

N.S.P. U.S. (ANCHOR) 7-41 Y.S.&L. Co. SERIAL NO. 31171

A fantastic & scarce example, ready for further research and display.
