The current Graphics set to the Chestplate of Vindication and Breastplate of Eradication are currently wrong. They are currently set to the new Velious armor graphics but in classic the appeared as a normal graphic plate BP.
The Chestplate of Vindication was a Grayish/Steel Colored plate BP
The Breastplate of Eradication was a black (like the Black Enameled Breastplate) plate BP
I cannot find proof for the breastplate of eradication but here is a link to LoS archives that shows their guilds first Chestplate of Vindication.
