Well, there are records on it and you can purchase a letter on it. Pictures would help us help you!
I suggest you go to the
www.parkerguns.org page and look at the link "Parker Grades" on the left side of that page. That should get you an ID. Also, look at the link "Parker Identification" and if you also look at the "FAQ" link make sure to see the bottom of the FAQ section and you will find a video that walks you through posting pictures to this forum.
Also, your user name should be your real name as you register. Then you can create a cryptic user name, this help us provide better security.
