After taking a diamond chest plate off of a armor stand and quickly breaking the armor stand after dropped two stands. The chest plate also despawned after a few go's at it. (Update- It seems that just right clicking the chest area then breaking the stand drops two and it doesn't always seem to work. Just had one that dropped three.)
