Knex K'nex Trampoline Tower #63517 Vintage 1999 Rare Complete Retired Working! This set is 100% complete (in fact there a few extra pieces included). It has the original K?NEX AC adapter. I?ve purchased and included an extra motor in the kit because I wasn?t sure if the one I had originally was working very well any more. So, there is a brand new motor included in this set! There was one blue square piece that needed a dab of super glue to reattach one of the tips, but it still works just fine! Also, I did not have the original instructions, so I printed a copy of them, and will include them with the sale. This is an amazing set! I?ll ship it the same day or next! Thanks for looking!
