I'm not sure why it was called a military brush - I know that they were often sold as pairs (used one in each hand at the same time) and were packed for travel by placing them bristle-side together - thereby protecting the bristles during travel.
I also suspect that these were never standard issue...not sure HRH would have ever spent this much on the rank and file and that they would have been the sort of thing purchased by or for officers.
