I am unsure what toy line this is for. It came from a lot that dated from the 60s to the mid 1980s; I would guess this was from the mid 1980s. Item is made of black plastic and is 1 1/2 inches long.
It will be for sale once it is identified.
I am working on turning Dollbit into a searchable database of accessories and clothing for a wide range of dolls, action figures, and other toys. If you can help with the ID of this item please post the ID in the comments or email me.
(Note: Two in inventory now.)
