As many of you know that of Alec Bennett with the Sunbeam "Long stroke" at the 1922 Senior TT was the last win for a side-valve machine at the isle of Man TT races. There is a shot that portraits Bennett and his Sunbeam at pag. 34 of "Isle of Man TT - An illustrated History 1907-1980" by M. Freundenberg. The caption is a bit ambiguous but seems to refer the shot to the 1922 Senior TT. Race number is 16.

But there is another shot on page 22 of the book "TT races - Diamond Jubilee 1907-1967" edited by Peter Arnold and published by the BP-Shell. According to the caption the shot portraits "Alec Bennett [/i](Sunbeam), winner of the Senior". The race number of the racing machine portrayed in the shot is 44.

So the question is: Bennett's 1992 Senior race number was 16 or 44? Is the shot with the no.16 taken from the 1921 Senior TT?

"Is the shot with the no.16 taken from the 1921 Senior TT?"

It seems it can not be as there is a Keig shot on pag. 76 of the book "TT heroes" by Mike Savage whose original white caption says: 'A. Bennett "Sunbeam" - Senior TT race 1921', and the portrayed race number is 9.
