Thanks for the info Keith,any idea when the book'll be available,would you have any info on the Sq4 of M J Gallagher shown here in the Dragfest featureviewtopic.php?f=4&t=1895
I am afraid I cannot add much detail about the square 4. It really is hard to believe that engine can fit into such a small machine.
It was not competitive, as it ran 15s/76mph at the 65 Dragfest. I would not like to have ridden such a dodgy looking bike!
Dennis Norman's was the best bike using that Ariel engine, running in the 10s when it held together in blown form. I will ask him about the Gallagher bike when I next speak to him.
As for the book, it is coming together well, and is due for publication in September.
