Can you use these old copper/brass fire extinguishers as kegs?

I was reading a few threads on converting a fire extinguisher into a keg. I like the stainless look but these old copper/brass ones are pretty neat. Can these be used as well?

No, copper and beer is a bad mix. Made a 3 tap tower out of one for a retired NY firefighter a few years back, wanted to use an old hydrant but damn thing weighed more then 100lbs, made the portable bar with 8.5 cf freezer top heavy kept wanting to tip over. Added a pole to it and made a floor lamp. E-bay has them cheaper if you watch.
