I need a help from you good GG people. I would like to assemble Esterigon and parts that I have are: Esterigon 18350 Tube Esterigon Venting Cap Esterigon Button Case Esterigon AD Ring Esterigon O-Rings What else do I need? I was looking spare parts for Esterigon section in store and on Imeos spare parts list but that doesn't help a lot. It seems there are so much parts that I am not sure if I need all of them or there are some variations depending what you want to assemble. Of course that I don't mean different size tubes or same parts in different colour/material, but still there's really a lot of parts. So I would really appreciate if someone could write what do I need beside parts I already have to assemble working Esterigon. You can use this page where all spare parts are to write down what should I buy: Esterigon Spare parts - The Golden Greek Store Thank you.
