Thanks for the heads-up, Jeff! :)
Bundeswehr M103s, huh? Hadn't considered that. Could look very cool, though. Awww, great, now I need two M103s. Maybe cross-kitting with some of the parts from Revell's upcoming M48A2GA2?
Yes, I am an agent of Satan, but my duties are largely ceremonial
I am curious to know if that Revell Germany M48A2GA2 is a new tool or a borrowed mold from another company with additional parts sprues for that version.
You could also try to use the engine deck from the Tamiya M48, M247, M60A1, M60A2, or the corresponding Academy kits of the same subjects. There might be clearance issues between the bottom of the turret overhanging the engine deck area but it is certainly worth a try.
As for the back story for that M103A1G/M103A2G: Perhaps it was a development to counter the Soviet 130mm assault gun tanks (such as the SU-130 or SU-152) that were assigned to special Front and Army level assault gun units located in the Western Military Districts of the USSR, the GSFG, and other Warsaw Pact countries that had USSR forces stationed within their borders that were field army or larger units.
