Hello,
Please let them know that people like me only want to document the flag for posterity and history and I do not need to even know their names or even where it is located now.
A good picture and detailed measurements of the flag would be very helpful (I can provide you with those needed based on how the late Howard Madaus used to do them).
Anything that can be procured for the study of this flag would be helpful indeed.
