I know the pillar and smaller wall are from 4111 Citadel internal walls. The big corner I can't be sheer if it's from 4103 Citadel Corners or 4102 Citadel external Walls despite having the original package which does not name the product, so I had to pull the possible name from minisListing.pdf (mutantpedia.com)
 Warzone Mutant Chronicles scenery pieces are possibly the rarest type of models from the Heartbreaker line on top of that finding any in as good of shape as my listing is near impossible package or no.
