Answer 1

You can take your gun to a gunsmith or try searching sites like Ebay for something similar to get an idea of its value.  

Answer 2

Go here for Value..> icollector.com, gunbroker.com, auctionarms.com, gunsamerica.com  ...The Model number is located on your shotgun , look it over completely, its there somewhere.*  The number 351458 is the serial number not the Model number..**
