The various Singer sewing machines in this group are all considered rare and scarce. They are "specially" badged and were sold at Singer's exhibit during the specific Fair/ Exposition. It's reported that some were ordered at the fair(s) and delivered later. Few were sold and fewer are known to exist. They make up the heart of our machine collections.
