This is a MPC Re-issue western cannon wall or battlement. In brown plastic, measures 8 1/2" long, 1 1/2" wide, and 3" tall. With log and shingle molded front, with window and notched firing ports. Piece does have 'notches' in floor and may have meant to be mounted on a taller Wall section? Good rampart for a cannon or soldiers in a variety of battles!
