@Setanta,
thats a WWII antique. Ive seen those at shows caus they were handed out by state police in PA. (The PA ones had a keystone symbol uner th word "GREASE". Then the grease was collected by some neighbir wag (Ive been told this by may mom in years past).
I knew the grease was used in the manufacture of glycerine for ammo and explosives.
Theyd make diesel esters and glycerine from the same operation. I dont know where other manufacture of xplosives was done xcept around Wilmington Del where the Dupont and Atlas works were.
