K'NEX 63153 Screamin Serpent Roller Coaster Motorized with Sound
- Source: eBay
Everything in near mint condition. I only set it up once, it's been stored since. Missing only 4 pieces, it can be fully assembled without them. See photo for missing parts. These include Serpent eye, two small black connectors, and a gray V connector. Every part was separated, and counted.This is a rare retired model. Motors and sound testing working perfect.
