Anvil Industries. Great sallet helmets

>what's the point of the missionary? Is it just an alternative model for a "priest"? Or did it used to be its own unit?
Yes, they used to be HQs/3W Characters/Personality models with open Wargear access (depending on how far back you want to go). Check the Sisters of Battle 2e Codex for the simplest version - it's also got some good Jes Goodwin art, so it's not a total waste of your time.

That used to be a Retinue model with a flamer, effectively a Veteran Guardsman.
>no real reason why
To stop people being able to make customized Command squads, essentially. There was more to it than that, but in 7th-8th you see a massive migration. People's second-tier HQs (missionaries, Palatines, junior Inqisitors, etc.) and any former Character upgrade to a Command squad (Ancient, Techmarine, Sister Hospitallier..) all become Elites sold as a blistered character model instead. They also snuck in a couple characters in the backdoor with things like Blackstone datasheets that let you proxy in old Special Character models who are now long-dead (Pious Vorne is The Redeemer, the new priest is basically Confessor Kyrinov)
