LaQ Expert L There are 16 Hamacron parts. There's a building instruction book inside the binder. Everything in the photos is included. I have purchased various LaQ sets, so some parts might be mixed. Regarding the weight, I apologize, but I don't have a measuring device, so please make your judgment based on the photos. If you would like additional photos, please feel free to ask. Thank you very much for looking. I hope that those who understand and accept used items will make a purchase. 3850
