I could not find a model number on a machine I bought at a thrift shop. I believe that it may be a very old model because it has only one option for baking (no size/pound option, no crust option, no type of bread option, etc.). Other than not having a control panel that supports a variety of baked goods, the machine I have looks like the typical Welbilt with the vertical container. As I said, it is a no frills model. Can you determine the model number from this description?
