On the "Discussion Forum" scroll down to the bottom of the topics to "PGCA Member Online Research Letter Requests", it's the 3rd from the bottom. Open that up and all the info you need is right there to complete the form and email it in and make the payment. If you prefer the slower method you can go to the home page, click on Research Letters in the tree on the left and print the actual letter request and send it in via USPS with a check, once again all the instructions are on the letter request form.

Not to say that this applies in this case but I would guess that people were working on and "restoring" parker guns since production stopped and probably before as well. We have seen from letters that Parker would take guns in and rework them, ditto Remington, even using aftermarket components or subcontractors. Others were likely up to the same, some reputable some less so. I hope the letter sheds some light on it but regardless thats a nice 16ga with known provenance.

Yup, 50 years is only a small part of the life of most Parkers. A Parker that is unmolested since 1970 is not neccesarily an original unmolested gun.
