I echo the call for WW1 French artilley (and crew). But I would rather buy the 155mm C15 or C17 Schneider, as the GPF made it to the front only late in the war and in small numbers, even allowing for the U.S. use.

All these guns were used by other nations later on, including the Germans. But it is the number of produced guns and the lenght of service history which make me definitely prefer the Schneider over the GPF.

There already is a 1/72 styrene kit of the GPF anyway, while of the Schneider, there is none.
