Bf110E/E2 Trop Fighter

I am a long time buyer of the Airfix products, more then 40 years. The reason why I only give 4 stars for this product is very simple, They did a very good job with renewing their models and I am sure that they are in the top 5 of the model producers.I,m sure that the model is going to be 100% OK. Why is the construction sheet printed in black and white and with this I mean the drawings of the models their colors, also the red warning sign for alternative parts, especially for the younger ones this was easier. Last thing, the models that we are creating are for a part history, why I must go buy my decals by an other company when I want to finish my German model with a Swastika ??? In order to make it more easy for the buyer, maybe it would be possible to make a little space free on the back of the box and print a list of the suggested colors on it, I am sure a lot of the customers would love this.
