Cast iron stairs cc/mod?

Hi all! I haven't really been to this end of the forum but I was hoping someone could help me out or direct me to a thread that could. I'm looking for cast iron stairs (railings/fences too if that's a thing, but I'd settle for stairs). I know that they existed at some point in either Sims 3 or 2 (or both?), but I have as yet to seem them in 4. I don't have all the packs and expansions, so there's a possibility they exist there and I don't own them. Does anyone know where I might be able to find some? Thanks a bunch :)
