Rifle Brigade Cap Badge - Opinions?

[FL517]

This badge was in amongst a family group I recently acquired. I be most grateful to receive any observations or opinions as to a time period and / or originality.

One member of the family was commissioned into the RB in 1916, but I have no idea as to whether this was his or has been added at a later date.

Any views would be most appreciated!

It looks a good quality badge albeit very dirty.

the two blades at the rear would confirm that is was worn by an officer.

No reason it shouldnt be the original from WW1.
