Military surplus, New Old Stock (NOS).

This set of three plates are used to adapt an M66 Gun Ring onto the leg mounting system on M939 series military trucks. (This does *not* include any gun parts, the gun tray, gun ring, mounting legs, or any bolts).

The adapter plates should still be usable on M39, M44 and M809 series trucks, but you might not need all 3 of the plates due to the smaller cab.
