Sadly, clearly, years ago, Jim did something to truly anger the lather gods. Now modern soapers have agreed to discontinue or reformulate every great soap he enjoys. Better stock up on Arlington, it's the only soap on his list that is still waiting for the axe to fall!
To be fair I used the pre-reformulated one with tallow... I hear the new Valobra soaps are a very good replacement for the discontinued AOS soaps. You are in luck as I have not tried them yet.... so its still available.....
