I use one gun model to represent two artillery pieces on the table. Here I have a howitzer (Perry I think) plus 3 Austrian 6 pdrs from Fife & Drum. The limber and horses are superb and come from Black Hussar. Although the supplied traces are fiddly to put on, I think they improve the look. I will probably have to do three limbers more to complete the Piedmontese artillery. But like most others, the expense and trouble of doing limbers puts them at the end of the 'to do' list.
