Another one of my older builds and right up there in my top 3 of favourites is Tamiyas CHAR B1 bis. The kit was an absolute dream to build and so much fun to paint and weather. I used many new painting and weathering techniques for the very first time, which just added to the satisfaction.
This was done as a full step by step blog during construction, painting and weathering.
For those interested in seeing this, I've attached the link below.
