came across a beautifull shotgun. double barrel side by side and appears to be a 20 ga. Says Remington arms on the receiver and has a 6 digit

serial number on the trigger guard but Remington has 2 letters on the left side of the barrel to go along with the numbers. This gun does not have those letters. I have to clean up this gun but I can barely make out some letters on the center of the barrel where it is knurled. any ideas out there?

if you have any suggestions please email me at

Thank you.
