Sounds like a Wafer Iron (Krumkake iron to a Norwegian!). Does it look like the picture inside?
There are two styles of handles, one that is a rod that goes into lugs cast into the iron, the other is a rod rivetted to the iron. Essentially no difference in value.
The hinge style is called a button hinge. I think you can see why. There should be a base this fits onto. The base is the most difficult item to find.
Complete, if I recall correctly, the wafer irons can sell from $150-$200, maybe a little more depending on condition. The paddles alone usually are between $40 and $60. Again maybe more depending on who is wanting one.
