some centre company men
These are the bases I used for my hussars - 12cm x 16cm.
I like the size and I'm going to get some more, cut lengthways, to use for my 79th. Each section will therefore be 6cm x 16cm and hold 2 files - 16 men in all.
For those units which I'm depicting in square there is enough space for 3 ranks.
For light companies out skirmishing I might use a whole 12cm x 16cm for just 16 men.
