I reviewed my Ohio files again and it appears that there were at least two variation of this pattern of regimental flag. The first one has the "thin eagle" I described. Such a regimental flag was provided to the 2nd, 6th, 7th, 16th 21st, 26th, 35th, 41st, 42nd, 45th, 54th, 58th, 59th, 69th, 76th, 91st, 96th, 114th and 121st Ohio Infantry. A very similar cavalry standard was carried by the 2nd, 5th and 10th Cavalry.
What looks to be a variation of this flag was also suppled to a number of other Ohio infantry regiments. This colour has a more robust eagle, but it would seem that both of these variations drew on a common original pattern. This second pattern of regimental flag was utilized by the 10th, 12th, 13, 16th(a second flag), 22nd (aka 13th Mo), 24th, 30th, 60th, 83rd, 93rd, 95th, and 125th Ohio. What appears to be a similar flag was also used by the 19th and 33rd Indiana. The latter flag, according to its inscription and the letter from John Coburn on page 240 of McCormick, "Indiana Battle Flags" (1929), was presented to the regiment by the "Loyal Ladies of Lexington" in early April 1862. As well, a similar embroidered flag was also carried by the 1st Kentucky Infantry. This flag is depicted on page 250 of the Federal volume of "Echoes of Glory".
