There are no British horse artillery figures in the Douglas Miniatures Crimean War range and so the options are to source figures from elsewhere or convert those that are available. I am keen to have as many Douglas figures in my collection as I can, so I opted for the conversion route. Using parts entirely from the Douglas range I think I have produced something that is acceptable. For the figures, I used the Douglas British foot artillery crews, with their coatee tailbacks and some other uniform items carved away. I also did a head swap from the Napoleonic British hussar figure. The heads were fixed by drilling small holes and using thin metal pins, along with super glue. For the limber I used the one in the range without modification, but had three outriders with six horses in the team.
