I notice that you live in Delphos, OH. I used to live in Celina for 11 years and have been living in Tennessee for almost 5 years now.
A couple things that might be helpful for you.
1) US unit colors made under contracts from the major depots (New York, Philadelphia and Cincinnati) were silk during the Civil War. This was because of their large size - 6 by 6 1/2 feet - and their need to billow so they could be seen in battle. US unit colors were designated to be this size since Von Steuben's regulations of the Rev War era - which basically copied British infnatry colors in size. Cavalry and artillery colors were, of course, smaller.
2) The flag you have in the video are not regimental colors but are the National colors. The regimental colors were blue with the US coat of arms in the center and the unit name on a scroll underneath.
3) The three depots, for their National colors, had varying canton styles and star arrangements. The star pattern on the flag you have is similar to that used by Baltimore flag maker Jabez Loane, except that he only made larger garrison and post flags based on my research.
4) There are some books that will be helpful to you. The late Devereaux Cannon's "Flags Of The Union" is a good overview for these flags. The excellent Time-Life book "Arms & Equipment of the Union" depict actual Union flags of all types and the three depots and their canton/star patterns are all depicted there.
Hope this is helpful.
