Whilst still in modelling mode I played about on Google images looking for uniform references. Here I chanced upon the cover for Osprey's illustration for the battle of Marston Moor. This picture shows the 'last stand' of Newcastle's famous Whitecoats wearing what I'd describe as personal shoulder bags. These, I realised, are easy to make in greenstuff with any detailing added with the scribe.
With the figure on the left, below, I tried to give the impression that the soldier had tucked his rolled up bonnet under his baldric. Looks it bit too big now but it will do for moment.
Painting of a few of the officers should start next week (honest!)
