OK, I can't tell if you are being a smart ass or not.....
I will clarify.
If it is a true production touring frame (cantilevers, rack mounts, loooong chainstays) from the eighties, there are not that many manufactures, they are quite distinctive. With a few (if they are the right ones) pictures you can figure out who built it by looking at the dropouts, BB, serial number, etc.
If you have a blank frame with no stickers, generic dropouts, hand stamped serial numbers, there is nothing (or very little).
And with that. I am done.
