You may have a hard time finding an exact match on the engraving. Your pattern may have been a 1yr offering or a later or earlier manufacture.
Like Jaguar said, you'll be hard pressed to find a local gunshop that knows anything about your gun. It really is a seperate catagory.
Go over to www.shotgunworld.com
and and post it there. You may get some useful information.
