I finished assembling one of the Pak36 kits I have. Not as fun and easy to model as the Pak40, but the Pak36 is still a very good kit and I highly recommend it. I will be replacing all my metal Pak36s with these new plastic ones.
Below is a picture of the assembled kit, but in my excitement of modeling, I forgot to take a picture before starting to paint. Believe it or not, that is not a black priming coat. It is actually my custom Panzer Gray color over a light gray primer - the first stages of many for painting. Looks black or black-gray, but its the same color as the Panzer 36(t) and Marder III (139) shown above. If you can believe that.
The kit goes together well and looks far better than any of the metal Pak36 kits out there. That being said, some care and attention needs to be done when assembling. Check the fit of parts and plan your assembly carefully. In particular, the fit of part E12/E19 can go wrong if you are not careful. It might be better to glue part E10/E11 first, but with care and proper fit, you can glue E12/E19 first.
