37mm Vigilante AntiAircraft Cartridge


I am in possession (not sure if that is a good thing) of a rather large complete cartridge. I believe I have correctly identified it (with the help of Tony Williams web site) as a 37mm T68 cartridge for the T249 Vigilante antiaircraft Gatling gun.

I’m not sure that it has been deactivated. It has a primer but the cartridge rattles as if it contains BB’s which leads me to believe that someone has removed the powder charge.

According to Tony Williams web site it seems that the Vigilante was a short-lived prototype weapon that was canceled before it really got used. Since this is the case I thought it might be rather rare.

Is anyone interested in this cartridge?
