Unknown case...... 60MM Spigot Shell, T-13

[ordnance]

This unusual cartridge case was found at the Louisville Show of Shows last month and I'm totally stumped trying to identify it. The base is ink stamped "SHELL, SPIGOT, 60MM, T-13" and a few other numbers that are too weak to read fully. As you can see, there is no primer hole and the general overall appearance is similar to the WWII naval hedgehog launching cartridge, just larger.

The T-13 designation would indicate an Army development but I'm unaware of any weapon system this would be appropriate for. Does anyone know?

Rim diameter................. 64.95MM (2.557")
Body diameter at rim...... 60.17MM (2.369")
Overall length................ 100.8MM (3.969")
Inside dia. at mouth...... 46.54MM (1.832")

Have you looked in Bob's book yet (cases)?

Looks like part of the Hedgehog spigot launch cartridges but not sure if it is 60mm? Similar item was listed on this forum but not with this headstamp.

It is bigger than a hedgehog case

Here is a link to one of the previous posts, with dimensions

I checked Hawkinsons book and he lists a 46x129R, with 64.8mm rim, 4 mouth slits, no primer as a large Hedgehog case. USA Navy.
