Well, if you guys have any doubt—I have no problem whatsoever with people customizing their KBs (or anything else) however they want to.
I'd just never seen anyone do that kind of thing with a vintage KB. Like I said, till now I had the idea that people who collected/restored old KBs (and lots of other vintagey things) went to a lot of trouble to make them as authentic-looking as possible, if anything. But it's a big, creative community and there are no rules.
I'm still learning about the whole cool MKB culture—by hanging out here on GH, because you guys know so much about it. But you needn't assume I'm some kind of villain... The way I see it, there are already enough people in the world who don't care about all this.
