Greetings again Alli.
I don't profess to be an expert in relation to this particular badge, I do have a couple of them, which I know to be genuine.
On this basis I believe the following probably indicate that yours is not a badge made for Regimental use and later altered to become a sweetheart item; but is a very good and apparently well made badge made as a sweetheart item:
Extra "flash" of metal around the front upraised claw.
Feathering on the top of the back is slightly at the wrong angle.
Gap between neck and wings is too wide.
Tail tuft too big.
I believe that all, (I may be wrong here though) O/Rs badges had a gaunt plate on the back.
There doesn't appear to be any evidence of your badge ever having had a plate.
There are also a couple of other points that you should see if you have a butcher's at those I have if you follow this link.

If you wish, I will send you a clearer picture.
Nevertheless, as I stated previously, it's a fab badge.
Best wishes.
