These are 28mm Late Roman heavy cavalry, Figures by Wargames Foundry. Now in the collection of Mick Hoddy of Herts Volunteers. Mick requested coloured lances rather than the usual brown, so I went for the green and cream/buff combination seen here. I think it looks rather nice if I do say so myself. It makes a nice change. I suppose it could be argued that there is no evidence for coloured lances being used. However there is also no evidence against it.
They will certainly stand out on the table top though!
