Product Description

    Marlin Model 90 12 Gauge Over/Under, 26 Inch Barrels, 2 3/4 Inch Chambers, 1950 G-Prefix, Blued/Walnut, Solid Matted Rib, Extractor-Only

    Marlin's Model 90 is a classic American over/under, and this 12 gauge example dates to 1950, confirmed by its G-prefix serial. It features 26-inch barrels with a solid matted rib, extractor-only ejection, and a brass front bead. The gun retains its blued steel and walnut configuration, with a 14-inch length of pull and Marlin's JM proof on the barrel lug. Matching assembly numbers on the monoblock add to its factory consistency.

    Condition

    Overall Condition: Poor condition.

    Bore Overall Condition: Fair - Generally clean, some residue or smudges, slight corrosion.

    Specific Condition Notes: The tang safety is very stiff and requires significant effort to disengage. The original blued finish has transitioned to a gray-brown patina. The walnut furniture shows handling marks, dings, and scratches.

    What’s Included
    • Marlin Model 90 12 gauge over/under shotgun

    This Model 90 is a boxlock over/under built by Marlin Firearms Co. in the United States. The G-prefix indicates 1950 production, and it carries a JM proof mark on the barrel lug. Matching assembly numbers appear on the monoblock.

    The 26-inch barrels have fixed chokes and a solid matted top rib for a clean, glare-reducing sighting plane. A brass front bead provides a straightforward reference. Chambers are 2 3/4 inch, and the gun uses extractor-only ejection.

    The action is break-open with a tang-mounted sliding safety. The receiver is steel with a blued finish, consistent with the blued barrels.

    The walnut stock features a pistol grip, cut checkering, a straight comb, and a ventilated recoil pad. Length of pull measures 14 inches, providing a classic field fit.
