Cheers Pete,
I would say early 20’s as the Sgt in the front row is still wearing a Brodrick cap. Your guess of 24/25 doesn’t sound that far out. My guess would be 23/24. I’m sure that that Sgt, wanting to be his smartest and up to date, would have swapped his cap to one with a peak. Wearing it 23/24 is close enough to the change over date to make it exceptable. Thanks again for posting the pictures.
Regards
Irv
