I have one of the Eatonia single shot versions, my buddy has the Ace.... they are pretty much identical.... if my memory is correct, they Eatonia's were sold by Eatons, not sure about the Ace... neat old guns but as someone mentioned above they are small as I believe they were intended for 11 - 13 year olds at a time when it wasn't so frowned up for the younger kids to do a little bird / rabbit / squirrel hunting
