If you are interested in the early Bavarians then you are in for a treat! Thanks to German historian and collector Uwe Wild (whose new blog History in 1/72 is a must-see) we have these images to look at - taken by him for his archive.
Here is a small selection from the battle paintings of Schleißheim castle. Depicting the Bavarian army in the Turkish wars of 1683-1715. See the grey uniforms of the rank and file, just the officers and NCOs had light blue at this time.
The artillery are from a painting of the siege of Ofen.
More to come...
