Old US airport identifiers

[pilot dude]

In the beginning of the 90ties I have been flying in the USA.

Im now trying to convert my logbooks to electroninc logbooks.

A few of the airport identifiers are not in the sytem and apperently they are no longer in use. I now have to create my own airports but dont have the airport names. If there is anybody that can help we with a name to the following airports,

Wisconsin Illinois area
C52
C13
C19

Texas area
T47
F39
E15

Thanks

PD

Google digs up:
C52 = KBUU, Burlington Wisconsin
C13 = K8N2, Ottawa, Illinois
C19 = ?

T47 = KCWC, Wichita Falls, TX
F39 = KGYI, Grayson County, TX
E15 = KRPH, Graham, TX

Not 100% positive of these results, but should put you on the right track.
