Looking for any information / value range on my auto 5. Based on the serial number records on the Browning sight I have determined that 1. It is an FN made Browning and 2. It is pre 1940. The serial number is 5 digit and the buttstock does have the FN logo on the plate. It is a 12 guage non ribbed 28" barrel. I would dare say for the age that it is in very good condition.
