Gary, the Serialization book was basically taken from the stock books. Grade 3 or high guns from the order books were added where a stock book was missing. So, where you have a stock book missing and we have an order book covering that same time period, the grade 3 and higher guns were added to the Serialization database. There is a list of stock books in the front of the Serialization book showing the books that are missing. In other words, where a stock book is missing, the only guns you see in that serial number range are grade 3 or higher.
