PART ONE OF TWO PART REPLY TO HAL
In its original incarnation as "Jewish Society of Americanists" it was over very quickly based upon available evidence.  The subsequent "Jewish Society of America" and its publication 
"Ideas: A Journal of Conservative Thought" also seems to have disappeared after about 2 years -- right?

My original point (perhaps unclear) is that fringe groups (like the Birch Society) often create front-groups which come and go very quickly.  

The larger point I was trying to make is that when you want to discuss the history of conservative organizations in the U.S, there are examples of organizations that were born in the 1950's-1960's which had a long and productive life and they attracted widespread support (even thousands of members) AND their newsletters had significant circulation but the Jewish Society of Americanists or their subsequent incarnation did NOT fall into that category.
