Luke,

The 9th London badge came in two sizes about 5mm difference between them. The smaller one has two voids and the larger a third with one under the horses belly. If it's a large one you're looking at and being un-blackened I suspect it is, then there are a couple of things other than the voids to look out for. The right hand cross arm has a die flaw and there is another, a sort of line crossing the U in South Africa making it appear uneven. I've seen this one all brass and whitemetal copies.

Attached both large (left) and small (right). You can gague the size difference by the honour tablet.
