If I can intrude? Surely if the press cuttings were used as a reference for the Col Stewart book that is sufficient substantiation? In what way to you want them substantiated?
Secondly, while the poster Jack Keen is criticised on here, is there an actual reference from him that he believes Johnny Hoskins started speedway at Maitland in December 1923? I have cycled through most of the messages in this debate and while he brings to light items written in support of Hoskins, he has so far as I can see not said that it is his opinion. My view is that all he has done is highlight alternatives to the views of those contra to"Hoskins started speedway at Maitland December 1923".
Doubtless I will be told that I have lost the plot in this matter, and that's not difficult anyway because there is so much contradiction coming from each side in regard to what the other says it is starting to get very difficult to get a grip on what is actually under debate, Basically, is Keen a Hoskins disciple or just giving the alternative view to those who have a varied opinion on the start of speedway?
