There are four guns in total, each being rated 9 pounders. Each has a crew of four some of which is pictured at right. My method of mounting the troops on short pieces of Dowel using blue tack is also illustrated here. I don't know the effectiveness of this type of mounting with 15mm or smaller troops, but with 28 mm and larger I think its a fine method of handling and painting the troops.
Though largely ineffective against troops and slow firing on the battlefield they certainly look good with the smoke amongst your troops and they come into their own against walls, buildings and other defences. They'll make a wonderful addition to either the Royalists or Parliaments artillery train.
