The main need is for Horse Artillery limbers and teams actually moving...not just trotting about...that is afterall what Horse Artillery units do, move, unlimber, fire, relimber, relocate, etc.
As for info on limbers, Franklin has written a couple of good books (with loads of illustrations) for the British, one on the Naps period (and the guns and limbers didn't change very much after 1815 until the end of the 1850s) and another on rockets used from the Nap period up until the 1860s.
Unfortunately, there isn't any limbers for Native troops, like the Sikhs. Moreover, the guns produced for them in 28mm (Foundry) aren't very representational of the vast array of guns they used. The guns are copies of the Sutlej guns held by the British. If you are in London you can see Sikh guns at the Woolwich Arsenal (hurry up before it closes and is turned into a housing estate!) and the Royal Hospital (Chelsea, outback). I think there are some other Sikh guns held in Dover Castle.
So how about someone doing a Sikh limber??? Don't worry, I will do my own using plastic card and such...it will be fun!
