In restoring old aircraft, NEW covering materials are used and consequently pinked tapes are sometimes used as the new material dictates. The covering materials used in WWI and prior did not require pinked tape.

According to many museums AND restoration people, pinked tape did not appear until some years after the War when new covering materials were introduced. Early aircraft used straight-edged tape and during the War, frayed tapes were introduced.

Windsock DataFile 36 depicts original N28's and straight edged tape is used as is shown in several places.

In scale modeling...RESEARCH,RESEARCH AND MORE RESEARCH is required to produce a miniature aircraft.
