Wow that .22 looks nearly identical to my Marlin. Same stainless finish, woodgraid colored stock. Only difference from appearance looks to be that yours has a clip and mine has the tube under the barrel that you fill with 15 rounds or so. Also amusing that you had a similar scope with over/under sights? Mine was a 41mm simmons if i recall.
Very nice .50cal, good luck w/ the sale!
