A friend who is not registered on the message board saw this and asked me to pass this on:
Scott Koen put up a couple of shots of wing parts. P/N NLC6031-47
DC-10 / KC-10 horizontal stabs have a bunch of NLC6031 dash numbers, but not -47, which may be a sub to something else.
The serial number 48209 may be the construction number...if it is...then the part may be related to USAF KC-10 79-1949, which is still flying...
Lots of NLC603X part numbers on the DC-10.
Pass this to Scott K if you are in touch with him.
