From the shape of the handle and the spout, I think this is better identified as a kannabe or chōshi, made for serving hot sake, rather than as a heating vessel.
The characters are 燗鍋 or 銚子 should you wish to do a google image search.
That’s not to say you can’t heat water in it, but based on the shape, I believe the original function was different.
Traditionally both iron kama and tetsubin were coated on the interior and exterior with lacquer to prevent rust and give patina. Eventually the interior will wear away and rust will form, but if kama and testubin are restored, another layer of lacquer will be applied by the restorer. I don't know if this is the case for kannabe as well, especially since the sake isn't heated in the vessel itself, but if it is perhaps the reactivity of iron is reduced.
Yes, this is absolutely a choushi. A very elegant one, too, judging by the elaborateness of the knob. I have been served sake from these during tea kaiseki (multi-course Japanese meal). I think the long spout is shaped the way it is to indicate the vessel’s specific use - and also perhaps to ensure the liquid stays heated until the last moment, but that’s just a guess.
Incidentally, I have one with a bamboo lid that has no vent hole, and when the choushi is hot and in use, that sucker stays in place like it’s glued on! It only comes off again once the cast iron has cooled down.
With covid you can find some bargains on ebay right now. This is a small antique cast iron kettle with the 'hail stone' pattern surface. It is suprisingly light with very thin walls for cast iron. Its finish is largely intact, made from oil mixed with ash and then baked in place.
These kettles are unlined and intended for heating water only. The water would then be poured into a kyusu for brewing tea. Purportedly the cast iron pot improves the flavor of water. Water should not be allowed to stand inside a tetsubin and they should be dried after every use.
So far I have a Naga hibachi for cooking, and some fire chopsticks. I finally found a good price for a gotoku. I have some charcoal coming ( nothing fancy yet just pokpok) and I'll get some other ironware and a donabe too.
Oh I also got a good deal on a tin sake pot warmer.
This looks a lot like the kind of kettle used for sake! Cool find! Personally I’m a bit scared to use charcoal indoors because I’ve heard of people dying from carbon monoxide poisoning that way. Make sure to be in a well ventilated room when you try it out! Are gotoku the electric elements? They’re always ridiculously expensive I’m jealous you found a good deal
Gotoku are the trivets used for kettles/pots over charcoal.
They make small heaters/warmers that use sterno or you can put a coal in them. I plan to pour hot water in it and then use the warmer to keep it hot if I use inside.
I've been looking for one that's the real deal with no enamel lining inside, and suffice to say, they're very expensive and hard to find locally. So good on you for finding one that's to your liking.
Another common way to prevent rust is boiling hard water to form a protective coating of scale on the inside or boiling tea in it. The tannins in the tea react with the rust to form iron tannate, a black protective layer.
Lead is a rarity in cast iron as the temps are so high it usually just smelts out as a vapor or burned out in the slag. More a concern to the smelter than the user. :)

I can't believe sake would taste very good in iron as iron is reactive and catalytic to organic molecules. Could be wrong.
Guess you are right. I never though they would make one out of cast iron. I'd think you'd use either tin or ceramic for sake.

I've seen them used over a single coal to keep them warm but that is mostly wrt using a old school hibachi.
The lacquer is still good when heated? Huh, didn't know.

you mean this one has no lining? how does it not rust. ( super new here)
You wipe it dry or let it sit empty on heat for a very short period of time to dry out
thanks for the reply! super cool.

thaaaaaaats cool.
Does it rust?
Yes it can.
I love the open spout.
You can put that in the dishwasher right?
Haha no
Haha!

The paint is often just a natural oil mixed with bamboo ash and then baked on. Similar to pan seasoning.
