I'll add my welcome to all the others. I've not thought of Alfred Andresen as a salesman, but I suppose that would fit. He struck me as an 1890s Norwegian entrepreneur that saw a niche market to supply the large Scandinavian immigrant population with the cooking, baking and other household goods they were accustomed to having in the old country.
It looks like your collecting/baking interesting might be a little similar to mine in some cases. I'm half Norwegian and like preserving the traditional cooking/baking. I started out collecting specialized scandinavian bakeware (like krumkake irons, aebleskiver and plett pans, goro irons, rosette and heart waffle irons). I like to use them too. Then I found pizzelle irons, they are like krumkake irons but a little thicker. Designs can be spectacular. Then I had to throw in the occaisional muffin pan. Thankfully I haven't been bit by the skillet variation of this collecting disease.
If you have questions about more of the Andresen products, the catalogs do show a lot and I have examples of most of the bakeware items that were sold and may be able to help you out. Even have a couple of the lefse (potato flatbread) rolling pins that are works of art. You can roll dough so thin you can read through it.
The reason I ended up here is there is an Andresen/Griswold connection. Andresen didn't cast his bakeware, but instead jobbed it out. Griswold made the bulk of his items after about 1905, may have before, but we've not pinned it down. Your waffle iron is a Griswold product.
You kind of have to have a screw loose I think to collect cast iron, but as I have told my wife, be thankful I don't collect tractors.
