Obverse Design Top has perched eagle, wings spread, head ducked down and facing right. This eagle has the wings swept down below the feet, and is very similar to the BG-10 (second badge type). This eagle is holding a banner in its mouth which goes up on the eagle's left wing (the right of the image). The banner has incuse lettering of "GUARD". The center of the shield has the second seal of the Canal Zone with a freighter going through the locks. There is a smooth circle around the inner seal with lettering which says "PANAMA CANAL COMPANY" curving above the seal and "* 1950 *" curving below the seal. These mottos are part of the second seal. Above the seal is a curving banner which has tails trailing up from either end. The banner has the word "MOTOR". Below the seal is another banner with tails scrolled up at either end. This banner reads "TRANSPORTATION". Below the shield is a smooth square for the badge number. The example above was never issued a number. The shield overall has a textured background. The shield has a raised ridge as the edge.
