I just picked up an eddystone with a 10-18 barrel and all parts eddystone. They all are parkerized. The stock has a P in a box behind the trigger gaurd, a capital letter A in front of the magazine floorplate, and a number on the stock end cap that is either 66 or 65. In some light the number looks like two E's. I think it is all original except maybe the stock.
Thanks for your help.
