Do you remember Lovestoneites?

[Babeufist]

They were neither Stalinists nor Troskyists: a third current in the communist movement of 30s.
I found the German group which is the successor of this International Communist Opposition: http://www.arbeiterpolitik.de/

PS
About the Lovestoneites you can write in the book entitled "The Right Opposition" (by P. Alexander).

[The Idler]

There's more than three currents calling themselves 'communist' and the CPUSA was not the first. Rather than looking for an alternative to what you perceive of as the 'first' and 'second' you're better off looking at political principles. Don't look to Lovestone for political principles.
