Kilgore was a big name in caps, and made some nice guns in the cast iron age, but by the time pot metal was king, most of their cap guns were second rate. That includes the Eagle. It ain't bad by itself, but next to your average Hubley, Leslie-Henry, Stevens, Nichols or Mattel weapon it's sort of an ugly duckling. This one's about 7 1/2 inches long.
