47th Div WW1 formation sign questions

[lettman]

Did the 47th Division actually wear the eight-point star sign (the so-called 'Dutch tile') on the uniform (either during or post WW1), or do all cloth examples date only from its use as a Signals Regiment badge? The WW1 divisional history (which is an excellent resource, by the way) seems only to talk about it as a vehicle sign, but Cole in Badges on Battledress (p.148) says that 'after the First World War, all units continued to wear the badge'. I'm also unclear as to whether it should be depicted as a square or a diamond, as the sources vary.
