I used to have them but had to remove all custom content for a while. I've been able to find most of what mattered but can't seem to relocate these.
They came in one set, I think they were listed under 'misc.' in the build section. CAStable, the one had a baseboard. The colours they came in as default were brigh green, red and blue.
They were a little cracked/mottled, which is why I remember them as being grungy, but they were just nice plaster walls.
I thought they may've been from club crimsyn but they don't appear to be.
I can't even find an old picture to show them.
I'm sure they're probably easy enough to find but I'm just lost. I've checked the Content List and trawled through the entire grunge/broken tag on My Sims 3 blog (Up next, the entire walls tag...!)
Any help would be great.

Thank you!
Really, thank you! (I was kind of on the right track xD)
