Many thanks, Youngtug. My father was an engineer by trade but, as far as I know, had no wheelwright connection. In the industrial West Riding of Yorkshire, machine tools were the usual forte of the engineer.
In his service notes, however, there was a reference to 'his horse' whilst training near Doncaster - he was late in bedding it out!!
On returning to the UK from France in Feb. 1919 he returned to his previous occupation as machine tool engineer.
Not many people about who remember the Royal Field Artillery, it seems to have become the Royal Artillery during the progress of the war. Only the 1914 -1915 star amongst his medals is inscribed R.F.A. The other two are inscribed R.A.
Thanks again, there may still be someone who remembers!
