I haven't a clue

Well I found these models in a antique shop nestled in amongst 3rd edition chaos marines and Advanced space crusade space marine scouts..  I have no idea what they are from , but curiously they fit into a citadel slotta base. They have a eldritch lovecraftian  horror vibe to me.. or maybe Agatha christiesque who'donnit characters   riding the orient express awaiting a lone murderer in the dark..
either way they are lovely things..
