If you check out some online pics you’ll notice there’s no flipper tab. The g10 on mine (and those online) is also highly polished and is contoured in a way where there is a horizontal pattern, not an arcing one as yours shows. The steel liner should also extend under the bolster on the liner-lock side, whereas yours appears to just have the g10 bolster meeting the linerlock instead of the extended steel liner inbetween those 2.
