We got this lot which was used, partially build. My son built them all again and tested them and put them back in the boxes. They are complete. (One we had to replace the rubber band on). I don't think we have all the gears, and they may not match the sets (they didn't originally come when we bought them), but we have some of them as photographed. 

Happy Building!!

I do offer combined shipping for multiple items. Once you are done shopping, send me a message and I will send a final invoice.

Note: In some cases, eBay automatically charges a purchase. In the case of multiple purchases where shipping charges are automatically charged, a refund for overage charges will be issued when the items are weighed and shipped. Thanks!
