Vintage large wooden crate probably originally for military/artillery use with  wording. It is probably used for carrying spare parts differential and other military engine parts.  Has some age related wear - see photos.  I have sympathetically cleaned the crate and given it a light coat of polish. You could do more such as paint the hinges, stain darker if you wanted to. Personally, I love the aged look. It would make a great coffee table (see pictures) blanket / toy box / toolbox

The image shows the text stencilled on it. The text appears to relate to military or logistical equipment. It suggests that the crate was used to transport a specific unit or equipment, possibly related to military operations, as indicated by terms like "PRED UNIT" (which might stand for Predictor Unit), "AZIMUTH," and the use of military-like serial numbers. 
This crate likely stored and transported a device or part associated with azimuth (which is a concept in navigation and artillery referring to the angle between the direction of an object and a reference direction, usually north).
