One quick deviation before we jump into some more World War 2 models.
A while back I based up one of the larger (105mm-ish) Scotia Micromodels Recoiless Rifles with some Heroics&Ros WW2 US artillery crew (so sort of on track for the WW2 thing!). This is again for my Argentine forces for the Falklands Project.
This shows the Scotia model a bit more clearly than some of my earlier shots. I think they fit together quite well.
