Identification RHA sleeve badges

[scammas]

Good morning
I am a new member. I am trying to compile a history of my family. One of my grandfathers rose through the ranks, gunner, bombardier, corporal, sergeant, BQMS), to become an officer in the RHA. His career took him to India and Egypt and he fought in WW1 in France and Mesopotamia where he was in charge of a BAC.

My cousin sent me a photo of his jacket. I do not know when he would have worn it (ie. to which part of his career it refers).

I'm wondering whether any of you experts could identify the badges.


Thanks
Susan
PS: I am not interested in selling them!
