This is a boxed set with parts to make four four 105/155mm C mle 1917 S guns with crew, Observer Rifle team, a Staff team and a Command Rifle team.
I initially decided that I would make two of the guns as 105mm L mle 1913 S guns.
Here are the two 105mm L mle 1913 S guns, I am using road wheels rather than spoked on these.
Here are the two 155mm mle 1917 Howitzers.
The completed 105mm L mle 1913 S gun.
I was going to make the 155mm mle 1917 Howitzers with the provided spoked wheels, however after thinking and reflecting about it, I decided that I would make up all four as 105mm L mle 1913 S guns.
