Picked this up at an estate sale. Nothing else at the sale would suggest, or lead me to conclude it's use. All but the center shaft is made of Brass. The three prong spaceship looking piece is spring loaded with the very end, with a fairly strong Spring. The other end is hinged, and slides back and forth easily. This end is "barbed" in such a way, it suggests they are inserted, expanded, and then used to pull something out??
Thanks in advance!
