That was probably a pin given to the mother of the Second class Scout at the time of his advancement ceremony.
About the only pin a Scout might wear on his uniform was the number of years in service pin. Pins had a way of getting lost and showing up in the darnest places, like your dinner or on the bottem of your foot, they were called pins for good reason.
If you've ever seen a picture of someone cooking for a large number of Scouts, they were almost always just wearing tee shirts while they cooked for that very reason.
