The pardner design is astoundingly similar to the Remington 870 design. Search for Remington 870 dissembly (or cleaning); I believe there are several Utube videos.
Yes, after some time of discontinue, Remington returned to building a 16 gauge 870. I will warn you that ammunition can be difficult to fine. Keep that in mind..
If this shotgun is indeed "like new", a Remington 870 of that vintage with a plain barrel would run around $225.00. With a ventilated rib.....around $450.00.

Since there is no one Remington 20 g model, there is no one answer. If the owner's manual (available free thru the Remington website) does not help, take it to a gunsmith.
You can contact Remington directly,and use the customer service site to E-mail your shotguns serial number and letter code found on the barrel.They will contact you with the year of production.
