Tyndall also a publishing company called Albion Press, and launched a new magazine, which he titled "Spearhead" after his former paramilitary group. "Spearhead" initially labelled itself "an organ of National Socialist opinion in Britain" and described Nazi Germany as "one of the greatest social experiments of our century". According to the historian Alan Sykes, this magazine became "increasingly influential" in the British far-right. The magazine advertised portraits of Hitler and swastika badges for sale. Much of the material that Tyndall wrote for the journal was less openly neo-Nazi and extreme than his previous writings, something which may have resulted from caution surrounding the Race Relations Act 1965. The GBM engaged in several stunts to raise publicity; in 1964 for instance Webster assaulted the Kenyan leader Jomo Kenyatta outside his London hotel while Tyndall hurled insults at him through a loudspeaker. In 1965, the group staged a shooting incident at its Norwood headquarters, claiming that it had been an attack by anti-fascists. In another instance they distributed stickers emblazoned with a portrait of Hitler and the slogan "he was right". In 1966, several GBM members were arrested for carrying out arson attacks against synagogues.
