The breed created by Dr. Albert McGraw, which he called Silver Spangled Araucanas (now known as McGraws), are never rumpless. The rumpless birds posted early in this thread would be better called Manx Rumpies. I believe they were bred by Dwight Scott of Ohio who was a friend of Albert's. It is my understanding that back in the day, Albert crossed Hamburgs into his Manx Rumpie population and did indeed have rumpless, spangled birds. Dwight Scott, having both McGraws and Manx rumpies descended from Albert's flocks could have favored the spangled birds in his Manx Rumpie breeding or bred McGraws into the flock, ether way, leading to the spangled, rumpless birds pictured by stoneunhenged.
As for the latest McGraw pictures I posted being Spitzhaubens, I would have to disagree. They are pictures of my McGraw flock and are being used to produce more McGraws.
