His cap badge is neither E Yorkshire or 2/3 Ghurka Rifles. That part I am certain about. However, the RE Kiddle cited does seem to be Richard Edgar Kiddle commissioned in May 1940 into the E Yorks (London Gazette 28 May 1940) and later with 2 GR - so perhaps wearing a cap badge from previous service?
Do you have any other photos for comparison?
