Ralph Davis has his own line of Lesser which is the original and came from the Platnium. He also has his own line of Butter which he imported after the Bells.

The Bells have there own line of Butter. The original Butters.

Then there are SGR Lessers. Im not sure if they imported there own Lesser or if they just have a nice selectively breed line. Anyone know?

If they are not the same, they are at least very very similar. Like Black Pastels and Cinnamons.
