 | | Does anyone have the Comborider instructions?
|
| I want the instructions for the big RoboRiders, but they can apparently no longer be found at lego.com. I tried to load the smaller riders, but they are all one big error. Are these on brickshelf or anything? (25 years ago, 5-Dec-00, to lugnet.general, lugnet.technic, lugnet.build)
