The set comprises of 40 Line Musketeers/Grenadiers plus a detachment of 6 Volunteer Jaegers which were attached to battalions. The 40 infantry will give you a full strength battalion at 20:1.
There are enough heads with covered shakos for all the figures in the box. In addition there will be heads with the Line Feldmutze and peaked Schirmutze for the Jaegers as Silesian units had them. Likewise the Jaeger belly pouch is separate as some Volunteer Jaeger units had them. Most figures are in 3 pieces as we realise people like to build up units quickly, so you have the head , equipment (knapsack, haversack, cartridge box, short sword and half the greatcoat are in one piece) and body to put together.
