This thing showed up on my local Craigslist and I could not pass it up:
It's a 228 oz Reynolds aluminum "Tapper" keg with it's own little cooler. Branded for Falstaff.
It opens up so you can take the keg out.
Obviously I want to adapt the keg for use as a homebrewing container. It's wonderfully portable and much easier than filling bottles out of the kegerator. Could also be a good way to do some cask conditioning and/or experimental partial batches.
Online searches haven't turned up much info besides the fond memories that people have of the "Tapper" kegs. They were introduced in the early 60's and ended up being a money loser because people did not bring the kegs back. Apparently most people just kept the things in their fridge, but the specialized cooler would certainly have been a primo appliance for your dorm room or bachelor pad.
Here's what the non-tap end of the keg looks like:
The white plastic piece (where it says don't tamper) is held in place by a metal ring, which in turn is held in a slot. The metal ring has a gap and you can push the ring further into the slot by enlarging the gap -- for example by putting a pair of needle nose pliers in there and opening them. If you do this, the ring no longer covers the edge of the white plastic. However, this does not in any way free up the white plastic piece, which is apparently attached to whatever is underneath it.
Unless anyone here has any ideas, I think i'm going to have to destroy the white plastic piece to see what's under there.
