I've been working on quite a few artillery limbers, lately - for Prussians, Wurttemberg and British. Featuring on this post are my first 3 limbers for the Prussian army. As there are no such kits dedicated to Prussians in plastic 1/72, I had to resort to some conversions, using HaT Austrian limbers conducted by Strelets Prussian Dragoons painted as train drivers.
I like to have 1 limber for each of my artillery batteries - and usually, 6 or 7 batteries per major army -so I'll have to produce some more of these at some point.
