Here are a few items from my forces that are not offered by GHQ...
My Romanian force has GHQ infantry, armor and transports. But alas there are no late-war Romanian AT guns, so I have acquired some Romanian M43 Resita 75mm AT guns from another vendor. This gun gives my force at least some measure of defense against Soviet armor in the first half of 1944, and German armor in second half of 1944 and 1945.
I combine GHQ and non-GHQ offerings to give my Romanian force some AT protection to span the whole war. From right to left we have the Bofors 37mm AT gun offered by GHQ in the Polish line, the 47mm Boehler/Breda gun offered by GHQ in the Italian line, a Pak 97/38 French 75mm gun on a German Pak 38 carriage, which is not offered by GHQ but was reasonably common in Romanian and Italian use in late 1942 and 1943, and the Romanian M43 Resita gun which is also not offered by GHQ.
I have built up only 4 AT gun crew bases, and I keep the guns loose, so I can have a battery of 4 (or 2 batteries of 2) for any particular scenario which might involve my Romanian forces.
These are my Italian Fiat CM 508 Torpedo field cars (more or less the Italian counterpart to the German Kubelwagon). These are actually made by GHQ, but not as you see them here.
They are offered in the Polish line as the PZInz302, as part of the kit with the 37mm Bofors guns my Romanians use. This vehicle was actually a Polish-built licensed Fiat 508 variant.
So with a bit of creating kit-bashing I returned them to their Italian variant, or at least a reasonable proxy of the Italian variant.
While we're on my Italians, these are Italian Autocannone 75 su TL-37s from my collection. GHQ also does not make this piece of kit, which is quite useful if one wants a mobile Italian strike force.
In particular they provide a bit of SP arty punch to my GHQ Saharianna recon units in Tunisian gaming scenarios. All of the crew figures, on both the Autocannones and the Saharianna, are from the GHQ.
The standing figures come from Artillery crews, while the seated figures are sliced off of the Russian seated infantry that comes in the 45mm AT gun / 76.2mm Infantry gun pack.
While we are in Tunisia, to oppose my Italian light forces I have built up some French light mobile forces as well. Here is a platoon of French AM50 armored cars. This interesting vehicle had a 37mm cannon and a machine gun sticking out of opposite sides of the turret. It had mostly been replaced in metropolitan units by the more modern AMD-178 armored car (which GHQ makes, and I have). But the colonial forces were still mostly equipped with this vehicle, hence its role in Tunisia in 1942/43. GHQ does not offer it, and quite frankly the quality of these models from a UK vendor is not great, but hey it's what I could get, and I got 'em.
They provided some punch to the French RCAs (Regiments Chasseurs d'Afrique -- African Cavalry Regiments), which were pretty much fully motorized by the time WW2 came around, using motorcycle troops, trucks for their support weapons, and AM50s for a bit of armored punch.
In my French North African forces they are teamed up with my French Motorcycle Company, made using the GHQ German Motorcycle Sidecar pack.
My French North African force also has some Char D1s, another model which is not available from GHQ. This was the heaviest armor available to the French to confront the Americans in Morocco or Algeria, and later the Germans and Italians in Tunisia, until some S-35s (which GHQ does offer) made the march from sub-saharan Africa all the way to Tunisia just in time to be shot up by Panzer IVGs in 1943.
The Char D1 also saw limited use in the 1940 campaign in metropolitan France, so these models can do double-duty. But they were rare in France itself, having mostly been shunted off to North Africa as France ramped up their re-armament program in the late 1930s.
So there is a sampling of some of the odd stuff that GHQ does not make that I have managed to find and add to my collection.
