Bidspirit auction | Three Marklin gauge I ?

Three Marklin gauge I ? American market passenger cars - Three Marklin gauge I ? American market passenger cars. Includes Pennsylvania 2942 coach, New York Central 2942 coach and New York Central 2943 combine. All nicely lithographed and in excellent condition as seen in the photos. The track that this would operate on would be 42mm inside the flanges of the wheels. The scale is between Gauge 0 and Gauge I so I am uncertain as to what it truly is.
