Great photo. That's not an OR's collar badge but he is clearly an OR.
The non-voided halo is also clear.
This is the collar with a much smaller scroll.

The longer scroll indeed matches the longer officers collar. Any date on the photo? Is it a WW1 TF Bn or a 1920s regular bn in India?
1908 belt with shorts with possibly locally made jacket with stand-collar. The badge on the side of the FSH is unusual. Pre 1924 pattern but could well be still in use a few years later.
