Just check the frame and fork to indentify some characteristics of the tubeset.
I can see that at the fork end of the steerer tube on the inside of the tube looks to be rifled and also shined a flashlight down the seattube and could see there's no obvious seam in the tubing.

Also indentified that i bird was stamped on the tube of the fork aswell as "spinner" was stamped on it.

Maybe this will help to indentify the used tubes.
