I got the powder. Looking at the MSDS it says Naccolith.
Rudman had this to say about naccolith
"Nacco Naccolith: (US)
This comes in a variety of sizes. In my limited experience of it (not available in the UK), this
developer easily produces warm brown Lith prints, but may be more suited to those who
like brown prints with less extreme ‘lithy’ properties."

He also said that the powder is a different manufacturer than the liquid.
That's quite evident looking at the msds for both. The MSDS for the liquid version looks pretty close to LD20.
