Jeff the View Camera Magazine Article on Gas Burst Agitation was in the May/June 2007 issue. I have the Kodak E57 publication that I received from Michael Kadillak he was very helpful, let me know if you need it.
I had three Arkay one gallon stainless tanks with floating lids that I wanted to use. I contacted Alistair Inglis about using one of his plenums in these tanks but it was the wrong size. California Stainless makes a one gallon Gas Burst System with exactly the same sized tank. I called them and although their plenums are made to be installed in their tanks they made one for me with a 90 degree elbow and hose attached. I installed the plenum at the bottom of an arkay rack that can be moved from tank to tank. Works great. You could just buy one of the Cal Stainless one gallon tanks/plenum and do the stop and fix manually. Finding the burst timer other than Inglis or Cal Stainless is becoming difficult. For the timer I found an Arkay BT210 on ebay and later found another Kodak Burst timer there.
At first I was using Xtol replenished and this worked very well but I didn't feel that I was developing enough film through it to maintain a steady state. I now use Pyrocat HD 1:1:100 and I also do semi-stand 1:1.5:150 and Nitrogen Burst works great for all of it.
Hope this helps
