Thank you for your kind replies!
Frank - I do not mean to make and resell anything!
I just want to re-cereate a tool bag for my car. I found a vendor on e-bay who will make it blue for me. For licence reasons he is not stamping logo, which is fair. I can do the logo myself (as you say, silk screen for instance). I asked the question if indeed it was always present because I was not sure if the logo has to be there or not - as I have seen a lot of original tool sets without it.
Mark, the search tool is my friend indeed! I think I am a Master of Search! Finished 2AM the other day on the tool sets. I really try not to bother the fellow members before I do my homework. Certainly saw the post you provided the link to and I have the pictures from it saved as reference for search.
I am certainly not sure about logo being more frequent later - now even less then before. Thank you for your hint about those logos fading - you may be absolutely right there...
