The last one I saw was in a Ford Thunderbird, I know, I know. Any way it was a perfect match to a 3 pound coffee can. The old all metal ones with the ribs around it. It did help open the headlights and was just on the inner fender. So what is the volume? Very rough guess: 4 inch dia. and 9 inch tall close to 113 cubic inches. So the 1/2 barrel size sounds about right. Keep cold and open with friends.
