DCLI Pugaree Flash - Boer War

[NR72]

Good afternoon all,

I am trying to find out what ORs had on their pugarees . I was always led to believe the flash was on the left side of the helmet only. I have seen the helmet in the Regimental Museum at Bodmin , which is just a red Cornwall Flash as below., maybe these were just for officers due to cost?? But having seen period photos of ORs they seem to have a bigger flash either side , and i cant seem to see any writing on it. It cant be just a red flash as i believe that was the RAMC pugaree Flash

Was their a written regimental order for the 2nd Duke of Cornwalls on where unit markings should be put on foreign service helmets, if so where would it be ?
