This is the German 105mm Howitzer set with a few additional pieces for the sandbag bunker and storage by Baueda.
I entered this set in the painting contest for the historical category at the Siege of August this past January. I was sure that if I won anything it would be with the limber in my previous post, but surprisingly, this set won a first place prize and the siege bucks given as a prize were quickly spent on some Testudo 28mm knights for a battle of Tannenberg (Grunwald) project. Had a great time at Siege by the way so come visit Augusta Georgia if you can next January!
Lots of nice accessories are included in the Bolt Action set - everything but instructions. I searched their site high and low but there were no instructions to be found for this piece, though I found instructions for about everything else they make. Hopefully I got it put together correctly!
