Just kidding their not for sale.... YET! This is what I am doing tomorrow. I have to cut the tops, drill 24 holes, cut 6 stainless couplers in half and machine the ends and tig weld everything. Should be fun! I got these from a big buy from Sierra Nevada they used to sell off old outdated kegs for $20 ones they couldn't use anymore. One we found in the dump. And 1 we got off craigslist. Its a German keg from 1996 was the stamp on it. Its not even Sanke is something weird I have never seen before.
Anyway wish me luck!
