I recently traded for an older 20 gauge 870 marked Remington Magnum Wingmaster. It has a 28" full choke barrel and what appears to be factory cut checkering but it is very straight forward & blocked with a series of three interlocking large diamonds on the beavertail. No curves, no fluer de lylse (however that is spelled) at all. The stock is more blond than walnut. It has a black & white line spacer on the Remington marked recoil pad and a flying duck on the the pistol grip cap. Any Rem experts out there? Is this just a standard 20 mag? Ken
