The push pins in the reciever are the same and so is the acorn magazine cap. The safety is in the same spot also. However, most finishes on the express are parkerized and the wood for the most part looks very cheap almost like cardboard "if you ask me". The wingmaster exibits better wood and also " in most cases" better checkering with ribbons and even fleur de lis sometimes exept for the earlier wingmasters that seldom had checkering and had the tootsie roll forearm. Also the wingmasters had a blueing on them instead of parkerizing. I like to think of the wingmaster as the beauty and I think of the express as the braun. But in the end both will give the same results....Game on the table
