Recently picked up a 1930's (my estimate) Swedish waffle iron (AB Skoglund Olson) on eBay. Haven't cleaned it.
I normally would not have purchased an iron like this as I have many examples. What caught my eye though is the extra handle at the ball hinge end.
The iron weighs about 8 pounds and is machined flat on the outside. About 8 3/8 inches in diameter. It is intended to sit flat on the stove. Flat topped cast iron stoves for both heating and cooking were/are common in Northern Europe.
Turning a waffle iron of this weight would be a challenge even for someone with forearms like Charles Atlas ;D.
So, this Swedish company added a nice assist handle.
I've attached a few pictures.
By the way, the design is the traditional heart shaped Scandinavian Dessert Waffle shape.
