no-logo PATB-1 with black baseplate?

[STLMTLHD79]

There are a bunch of these for sale on Reverb right now. I have been tempted to pull the trigger on one. Why do they have black baseplates?

The one's I'm seeing have a logo - it's the Trembucker / SD logo. Black baseplates is a shop floor custom option. Anyone can get it.
