Manchester introduced their Park Avenue pattern in 1931. The design itself is fairly simple, however the serving pieces are fairly ornate. Take the Cold Meat Serving Fork - I have never seen such an ornate piece. It looks to me more like a Tomato or Cucumber server in other patterns. Also note the unique style of the butter spreader - more modern than most 1931 patterns.
