An assortment of action figure Hands, Arms, & Legs which have avoided identification over the years. Maybe one or more ignites a memory?
Some ideas (though I've struck out searching the mentioned threads):
the light blue Arm with Hand & 'Gauntlet' seems 'Boba Fett or Jango Fett' like;
the 'Alien' Arm with Hand, & the Leg (in the horizontal 7-9 range) appear 'Star Wars'-like;
the large dark red leg has a 'Lego'-type connector;
the black/green/khaki Arm with Hand has a 'Halo' look about it;
the black & orange Arm with Hand seems similar to one for Crash Test Dummies;
the light blue Arm with Torch is marked (AR3);
the large 'Armored Knights Fists' pair are marked (7015-2159 4, & 7015-2159 2);
the small dark silver 'Gloves' pair are marked (2086-01, & 2087-02).
All are a mystery!
