I was able to track down a couple other black smoke formulations that may work, I can send them to you if you want.
Generally speaking all of the smokes I have are based around either dyes, an extremely slow burning / smoldering pot, or a system of oxidizer (potassium chlorate or nitrate) + carbon source(s) (charcoal, HCE, lampblack) + anthracene and/or naphtalene; some are modified with aluminum, magnesium, sulfur, realgar, or stearin. There are also some based off of zinc like the Ellern's I quoted above.
Here are some examples of the more interesting ones. As always, caveat emptor:
Smoke, Black Intense
09.5 Potassium nitrate
00.5 Asphalt resin
50 Cupric oxide
35 Lead dioxide
Black Smoke Pot
70 Potassium nitrate
30 Red gum
10 Barium nitrate

Perfection does not exist, but that does not mean you cannot work constantly to attain it.
The really important kind of freedom involves attention, and awareness, and discipline, and effort, and being able truly to care about other people and to sacrifice for them, over and over, in myriad petty little unsexy ways, every day. . . . The only thing that's capital-T True is that you get to decide how you're going to try to see it. You get to consciously decide what has meaning and what doesn't. . . . The trick is keeping the truth up-front in daily consciousness. -David Foster Wallace
