Under reference ARTITEC 387.439, here's a yellow catenary inspection scale, to scale HO 1/87th.
Artitec's ready-made models are authentically handcrafted from resin and etched metal. Each model is hand-painted, sometimes subtly patinated to create a realistic look and feel. These models are unique collectors' items.
This scale will ensure that the catenaries on your HO 1/87th scale network work properly.
