Lord of the Rings Plastic Figurines DnD, RPG Ambush at Weathertop LOTR

Nazgul Black Rider with sword Frodo and Sam Rider with lance and horse. Horse reins are split. Looks like they used to have a base of some kind? Horse and Nazgul are free standing, have a notch and peg on their feet, as if they fit in a base of some kind. The hobbits with their cloaks and the ringwraith look to be the Comicon Edition Convention Exclusive Twilight Ambush at Weathertop edition, but check the photos and make that judgement - I am not a toy collector. Please see photos, ask questions!
