An interesting observation revisited today on my Juncker-cored Juncker crosses - the core is convex both from the center of the core to the end of each arm, and, is also convex 90 degrees off of this length. To really see this one needs to lay a straight piece of paper on the core in front of a good light source. You'll see light coming from under both ends of the paper while the paper is resting on the core. I am aware that Juncker used W&L cores in their crosses, but have found that these cores are perfectly flat, no convex shape to them.
Here's a photo of a non-vaulted Juncker with the 1st pattern core showing the convex core shape...
