Double spout cast iron kettle

very unusual double spout kettle 13" long from spout to spout 7" tall not including the handle

spouts have 1" openings top opening is 2 3/4" handle has old wire and old piece of pipe for the handle

front of the kettle has embossed letters of NSCO as seen in picture #4 back of kettle has an emblem with NS over CO as in picture #2

nothing is on the bottom No chips/cracks very heavy looks like lead in the inside bottom may have been used in the civil war

I also heard it could have been used on the railroad I have never seen another one like it
