Can anyone shed some light on what is going on here.

I would normally expect to see a seal similar to this standard setup in the first pic.

However when I pulled off the drum it looks like the seal is in two parts (or maybe broken, however both drums are the same). These are ALKO brakes, on a horse float.

So:
1. Is this normal?
2. Can I replace with a normal seal?
