WW2 Artists Rifles Uniform Insignia & Buttons

[Salpe86]

Hi all

I was hoping to get some information on these Artist Rifle patches and buttons.
Would these be Second World War era or later?

Thanks in advance.

They are WW2, and the badge is 163 (Infantry) Officer Cadet Training Unit.(Artists' Rifles) based at Shorncliffe. My father passed through it briefly.
