Eduard is planning to release a pre-painted injected plastic PSP base. The base has a copyright of 1999 in the back, so I think it is the “old” PSP base which now gets a pre-painted treatment.
What about the pre-painting? It is great. Deep browns and grey shades, with a touch of lighter spots and rusty shades. This is not just pre-painted, it is weathered, too!! Now, be aware that the sides of the base are left in bare plastic (white). You might want to consider painting the sides to match the colors of the top and maybe to apply a wash to the overall base to bring out detail.
What is the quality and detail of the plastic? It is outstanding as we became used from Eduard. No flash or molding flaws. Clean and crisp details. The dimensions are 164 mm x 234 mm. It will fit a P-51 just fine, but it might be a bit tight for a P-47, as it is shown in the pictures.
