First released in 1952, there were 18 animals that came with the BY-4 set. This same quantity would also be in the 1606 box when it was released in 1957. These animal sets consisted of four sheep, four pigs, three horses, four standing cows, and three sitting cows.

Illustrated below are the color varieties of these animals. Some colors are more difficult to obtain than others. The RED BROWN variety of any animal is particularly tough to find, as is the WHITE horse. All varieties of these animals are needed to complete the sets that I have.
