I suppose that this question may be a little off topic , but I'm sure that there are some very knowledgeable 870 fans here . I have an older 870 , and according to Remington , the serial number , and barrel code place the production date at 1967 . It has the standard Wingmaster markings with the original blued finish . It also has the standard walnut checkered stock with the hard plastic but plate , "no rubber recoil pad" . To the point of my question , the barrel is 20" long , but was clearly marked FULL at one time . The FULL marking was neatly peened out , and CYL. restamped below it . This looks to be a factory conversion , but according to Remington , they never did this . I have seen older shotguns that were cut and restamped , such as the WWII era riot guns , but nothing this late . It certainly does not look like a bubba job , but a factory machined restamp . The CYL. marking looks roll stamped , and not individually lettered , just like on another 870 I have with the CYL. marked barrel . It has the bead sight installed , and also looks to be original . Any comments or opinions would be appreciated . THANKS !
