Ok, so i'd like to think that I've seen Sally a few times. I've found or been invited to over 200 rainbow sally's since I started counting, so I've got a fair idea of what to expect when I see her. Here's the question.

Cooper's cooler splint
(latin word meaning "same" that is censored) eructus stirups
Rigid Milwaukee brace
Ichabods cap
foil covered thinkbox
ultimate rush
And a few other's that i can't think of off the top of my head

I've never seen any of these items at any sally. . .ever. Not at any level whatsoever (is that one word? sounds like it is). Are they simply not something that Sally keeps in stock? Are they left over items from a previous chunk and no longer availible? I've never gotten any of them as a drop either, but that doesn't shock me being as I've probably gotten less that 100 rainbow drops in total.

As a side note, I saw someone who had peacock (or was it cockatrice) feather armour on snarky's xml viewer. looked like purple splint armour. Never ever had that as a drop either. Am I that unlucky?

Sally sells all rainbows, I can tell you that, but some are mroe rare then others.
For the feather armor.. what is the name of the eprson wearing it?

Yeah... Unique Splint (looks like Cooper's) is Cockatrice Feathers.
