NOS means new old stock. These are items that are still in new and unused condition that have been on the shelf or in storage for a number of years. Most of my items are in the original factory boxes or cases. Some of these boxes show a good bit of wear and tear from storage time and handling. I try to add to my store listings all the time. Please keep in touch. Most items are sold "AS IS" with a "no return policy" unless stated otherwise in the body of the ad. Please know what you are buying and ask questions if you don't. I will answer all emails to the best of my ability. If you are not satisfied with your purchase please contact me immediately. I am not an expert concerning much of what I sell. Please send part numbers when inquiring about certain parts. Sincerely, Mike ... Don't forget to click on SEE ALL CATEGORIES in the left hand navigation bar.
