I almost forgot the one that got me first hooked on 1/48 armor.
The Tamiya Porsche turret King Tiger.
Yes I remember my first 1/48 scale armor was the very same tank. But it was made by Bandai, which also offered the Tiger I ausf E, Panther G, Pzkw IV ausf D, Wespe, Elefant and 251/1 Half track et.al. What I really liked about Bandai is that they had full interiors to build. But then I discovered the 1/35 scale and I was hooked. But still 1/48 scale is very nice indeed.
