A webpage listing all the convergences for each plane and showing which color = which gun for that particular plane. On the majority of the planes I have no idea which color is what. Take the mossie for instance, how would you know what gun is what! I'm sure alot of the vets have memorized each color for their particular favorite rides. A list of these would be well worth the time to create it. I know I would use it and be be grateful for the data collected. What do you think?
