This is an original industrial machinery identification nameplate manufactured by the Koehring Company of Milwaukee, Wisconsin, for the Traildump heavy equipment model. The rectangular plate is made of brass with a black background and red and black enameled details. It features the Koehring Heavy Duty circular logo on the left and stylized company and model branding. The plate contains un-stamped fields for size, number, and approximate weight, suggesting it was an unissued replacement part. Patent numbers 2173441 and 2189186 are listed at the bottom along with the designation 4221B172 in the corner. There are four mounting holes, one at each corner.
