Nautical Screw Room plaque / sign. This one is Solid Brass and has raised brass letters reading: SCREW ROOM
Meant for the area of the vessel where the props go through the hull, but could be placed just about anywhere.
Measures 1.5"H x 6"L. Beautiful, shiny polished solid 3/16" thick brass plaque.
The photos don't do justice, as these plaques are very crisp and defined but shine back so much light to the camera.
