Will: go back to the Home Page and click on 'Shotguns'-you'll be able to research the grade and date of manufacture. Lots of pics on 'Photo Trail' and lots of answers on 'FAQ' If you still have questions, please post high resolution close up pics of the flat part of the receiver, flat part of the barrels, and both side plates. Be sure and fully open the gun to cock the hammers before disassembly, and don't let the hammers down or you will be unable to reattach the forend. Hope that helps.
