I found one a lot easier by searching for comet. There's the bayonet mount that fits more securely on the sh2000 though.
I consulted Photoflex, and they definitely have a different speedring for Comet vs. for Dynalite.
Same applies to Chimera, too, differentiating Comet from Dynalite.
(Chimera has four different speedrings for Comet heads, while Photoflex offers one and says it is not compatible with two Comet models!).
The Creative Light 100835 Speed Ring is a bayonet mounted speedring for attaching softboxes to Comet flash heads, and is also compatible with Dynalite SH2000, AH4000, SH4080 and 4040 heads. Creative Light also offers another ring 100828, for other Dynalite heads.
The Plume speedring is also stated to be for Comet and Dynalite 4040 heads, but the illustration shows no bayonet mount.
