In the end I decided to modify each figure in the same way I did the test figure, by snipping off part of the hat brims and building them back up using Magic Sculp. I did tentatively try bending the metal as suggested by Rob, but it felt like the whole head would snap off which was not the look I wanted.
I found this blurb somewhere on the internet, can’t remember where -
The first commander of the Regiment (consisting of 444 officers and men, chosen from 5,000 volunteers) was Colonel John James Scott-Chisholme, who led the unit at its first engagement, the Battle of Elandslaagte on 21 October 1899. During this battle two Victoria Crosses were awarded (to Captain Charles Herbert Mullins and Lieutenant Robert Johnston).
The Regiment subsequently saw service at the Siege of Ladysmith (where another Victoria Cross was awarded - to Trooper Herman Albrecht at Wagon Hill) Colenso, the Battle of Spion Kop and the Relief of Ladysmith. At Spion Kop, the ILH was successful in capturing Commandant Hendrik Frederik Prinsloo, the commander of the Carolina Boer Commando. The ILH was then specially selected to join the Mafeking Relief Column under Colonel Mahon. Eight men under Major Karri Davies of the ILH were the first to enter Mafeking on the night of 16/17 May 1900 to break the siege.
The figures are by Newline Designs except for the Officer who is converted from a Raventhorpe Miniatures Boer.
