Abstract
Abstract A folding tool case operative to stand upright on rollers when open to present for use tools removably supported upon the opposed inner vertical panels of the case is described. The particular location of each tool of a set of various tools supported in the tool case is identified by shadow representations of the tools painted or otherwise marked upon the case panels to minimize tool loss while at the same time providing ready access to the tools during their use in engine overhaul.
