Heheh... I keep finding these old threads to spin up! I actually have a Charatan Special Group 4 that I purchased in 1978, and I am currently sleuthing for historical facts and dating. I will pass on the stuff I have found so far that evidences when it was produced and what the nomenclature meant. I'm surprised at how much information was actually out there. I haven't gotten photos of this one archived yet, but will put some up as soon as I can get to it in a couple days. I find all this history stuff to be quite fascinating!
