I needed a diaphragm and stem for one of my Super63s. I looked on eBay, none. There were a couple listings by Everythingairbrush in the UK that I saw. I know that EverythingAB is the place to get Aerograph/DeVilbiss parts. I contacted them through eBay and heard back from Tim. He explained the ordering process. I ordered two diaphragms and stems (to have a spare), a fine line nozzle and two fine line needles off of their website. I placed my order around 5:30 am on a Friday. They were in my mailbox the following Tuesday. 4 days from the UK to Pittsburgh. Incredible! I don't know when I will need more parts but I will not hesitate to purchase more from them again.
