We are an eBay Store that sells for many different customers. The 3 letters in parentheses are for our internal customer inventory tracking. We are not experts in any field. While we make every effort to accurately describe each item and any flaws it may have, it is YOUR responsibility to make that final determination. Please examine photos carefully to make your own condition determination. We only accept returns if the item does not arrive as described. All items are sold AS-IS. All items will be shipped insured for the purchase price.
