Many many thanks for you nice opinions!
Regarding the vehicle, is completely real excepting the flak. There are some pictures which show a RSO with a special support (the support Oscar made is an exactly reproduction of the real support) with a Gebirgsflak, an specially designed flak for mountain soldiers. Jorge just changed the Gebirgsflak for a Flak 38 in a "field workshop" conversion (as far as I know there´s not any Gebirgsflak kit)
This vehicle, will be included in a vignette with 5 figures.
Here you can see the nearly finished vehicle (the pictures above were 90% finished, step by step pictures), including the second door, more weathered cargo plataform, painting details (disastermaster, the painting detail you said was still missing,in fact, as the vehicle is abandoned, over the bare metal of the wheels teeth I made some filters using rusted colors over them)
Anyway, the vehicle is still not 100% finished. As Jorge will include it in a vignette, the final touchs (some dust in the road wheels, spare cartridges and ammo boxes here and there, accesories, so on), are still missing.
Hope that in some months, my friend Jorge will finish the vignette!
Thanks for posting
