The padded armour of the cavalry mark them out as New World troops but they would do for Spanish, French, British or Dutch. As an aside - once I stuck them to the base they listed very badly to the left so I had to put a weight on each horse in turn. They have straightened up ok but I have this niggling feeling that their socialist leanings will re-assert themselves.
The artillery are pretty generic so could be used in a wide range of Renaissance armies e.g.30YW.
Between photographing these bods and the 15mm figures something happened to the camera's focus. Hopefully I can sort that out and post the rest tomorrow!
