I recognized the claws from "Yarnek" on the "rock monster" Johnny Olson was wearing, but were those "pieces" of the Horta repurposed as part of its hunched back? From your fannish nostalgia it's kinda' a shame props, set pieces, costumes, etc. often get carved up like that, but I also realize that for most of these professionals, those things are merely "resources" to be used as needed, not invaluable "artifacts".
