Part of the allure of vintage cast iron, besides the fineness of the castings, are the unique trademarks and detail work the foundries of the past cast into each piece they produced. Pattern makers were both skilled craftsmen and artists, in some cases even carving small, unique figures ("maker's marks") into their work to identify themselves. There are instances, however, where the parentage of some 20th century cast iron ware seems mysteriously unclear.
Much of what's known to collectors as "unmarked" cast iron has quite a bit to do with marketing. In addition to store brands, like those made for companies such as Sears Roebuck and Montgomery Ward, several major foundries produced unmarked versions of their goods for sale in hardware, department, and building supply stores. As such, these no-name pieces could be sold at a lower price without sacrificing the brand image and value of their main product lines. Product differentiation in the various channels was achieved by the use of paper labels affixed to the unmarked iron. A couple of manufacturers actually made the decision at some point to cast all of their pieces without trademarks, instead relying totally on the adhesive labels.
What's interesting about unmarked pieces is they are typically similar if not equal in quality to their marked counterparts. While the majority are not considered collectible, per se, they can represent excellent value as "user" pans, and can usually be obtained at a fraction of the price of comparable fully-marked ones.
Here are some unmarked pieces you're likely to see, and information on how to identify who made them and when. Some of them actually enjoy collectible status. Bear in mind that, as with marked pieces, transitions between designs did not necessarily occur abruptly, so all dates given are generalizations.

While unmarked pieces produced by the major manufacturers can often be identified, those made by the myriad small foundries of the 19th century and earlier usually are not. Typically, the only characteristics which distinguish these older pans are confined to molder's marks (usually the foundryman's initials) or a decorative handle style. Sometimes, certain designs can be narrowed down to a particular century or part thereof, or to a geographical region. Or, if there are marked counterparts of identical design and dimensions, that may provide a clue. But, knowing exactly who made these early pieces and when, however, is more-often-than-not impossible.
