Mike:
The circa 1998 series I assume you are making note of was entitled "The West" which had figures of Lt. Col. Custer and his 7th Cavalry of 1876, plus their assorted American Indian enemy at the Battle of the Little Big Horn in what is now the state of Montana in the Southeast corner. I am afraid you are beating a "dead horse" on this one. I was after Andy about this subject between 2005 and 2009 and finally gave up when he came out with his circa 1850 U.S. Army 2nd Cavalry and lower plains Indians instead of his going back to the 1976 7th Cavalry, etc series.
