Here is a catalogue listing for a vintage enamelled-on-steel kettle. The cost for the 4 quart size kettle was $1.35; the 5 quart size cost $1.58. The ad is from the 1897-8 H. O’neill & Co. catalogue. 
Here is a black and white clipart version of the kettle.

Wonderful kettle – aren’t the prices a kick! Thanks so much for bringing us such fun items.
Thank you
You’re welcome Elaine and Angela. I enjoy seeing what the prices were like 100 + years ago. 🙂
