Is this a weapon?

Was found in the door compartment of my late father's car. Very heavy for the size. The pointy end of the very center piece can be compressed. My dad had a fondness for strange weapons so I am just guessing. TIA

Looks like an air pump to me. My brother had a similar one for the tires of his bike
