This is a project from the last week, for a local hobby club, a Gruson Fahrpanzer (one man small bunker with a cannon). Used by the Bulgarian army in in World War I, 30 were bought from the 5.7cm variant. I designed it with the small 3.7 cm cannon and 5.7cm cannon. Separate parts for the turret, body, wheels and cannon. I will print it the next days.
The majority of Farpanzer had a two man crew commander/loader and gunner. I think only the original proposals were single man crew although I must admit there were numerous design variations and several gun sizes fitted over the years.
Wow that really looks good. As well as the mobile self-contained systems the German also used the turret on some of their early post WW1 armoured trains. The turret was mounted on a 4 wheel open style high side cargo wagon with the top enclosed.
