Favorite Tea Kettle

Picked up a tea kettle today for $18.

The lid is marked: Favorite Stove Works Cin. O.

It has a raised 7 and a gate mark on the bottom.

I'm thinking 1890s. Am I correct in thinking that most older tea kettles do not have the manufacturer on them?

Can someone estimate it's value?

Favorite Stove Works was in operation in Cincinnati from 1880 to 1888, after which it relocated to Piqua and was renamed Favorite Stove & Range Co. Value would be dependent on condition. Actually, it seems the most often marked items from the late 1800s are the tea kettles, e.g. there are no skillets marked Blacklock, but there are tea kettles, sad irons, etc. that are.

It appears to be in good condition with the original rectangular bail.

Can you please estimate the value with it being in good to very good condition?
