Three titles for identification

[Milmed]

Found these recently and need positive ID please.

1. MMG sheet brass cut out with brass wire loop lugs - was thinking 'Motor Machine Gun' but title typical of South African WWI cutouts!

2. BH in sheet silver, attachment broken - Was thinking Boer War 'Brabants Horse' but need confirmation

3. DG sand cast brass with cast lugs - Was thinking Boer War 'Dragoon Guards' but also need confirmation

Positive ID appreciated.
