The owl-eyed tiger is also available in bi-metal. I would be wary of this badge as I don't believe that the die is original to the period of wear. If I was being generous you might regard it as a contender for a CCF badge: although the school CCF bagdes in recent years have bronze finished.
It is very unlikely to be pre 1940 and an OTC badge.
