aluminum or stainless steel
Howdy, that keg looks like one I bought a while back, when I started cleaning it up , I found where it was stamped STAINLESS STEEL. I bought it the local scrap recyclers , some one had cashed it in as aluminum, I got it for 45 cents a pound scrap price. It's gonna look good on the back of my '29 Model A rat buggy. Happy CRUISIN'
