uk, here is an attempt at a somewhat old-fashioned looking logo. It's not really "old" looking, it's still modern-ish, but it's not futuristic or anything.
I think the desaturated version (grayscale - no color) helps give it that classic feel that you asked for, but if you still want me to add some color to it, just let me know. I can also resize it if you need me to.
