GDG- Union flags captured at Gettysburg

[Biggsk at aol.com]

hello,
 
I cannot recall if I have posted this request before or not - and if I have  
it has been quite some time.
 
An acquaintance is compiling a list of Union unit colors captured at  
Gettysburg and needs some help.  My expertise is much more for CS flags so  this one 
I am not able to help with much - hence my request.
 
If anyone - or any group of anyones - knows, please let me know by private  
email (unless the list might also find it interesting too).
 
Thanks in advance,
 
Greg Biggs
