Yes, that’s what I’d meant, the double layered part loosened and divided. You will probably know that some men actually did slit and then plait the strap before passing it back through the brass adjuster. The securing the badge in place fashion seems to me to have been a bit of an ‘old sweat’ thing. It’s often seen in informal photos, but would have sent most sergeant majors apoplectic on parade. For some reason it’s seen quite a lot on ASC men and was derided by the smarter regiments, Guards, etc. as like a b****y “tram driver”.

Thank you for that information.
I will start the research next week on the additional I formation.

I would imagine a fair number of those Great War ASC men were actually ex-tram drivers.:)

Yes, I think that’s what was being implied Hoot. Even females attached to the ASC.

I believe those girls in the photo served as ambulance drivers at the military hospital on Cannock Chase. The one badged as RE was probably attached to the military railway in the same location.

That sounds eminently feasible, Hoot.
