Companies would release miscellaneous patterns, usually without a name just a number that were just one piece designed in a series. This is one such pattern by Baker Manchester of lovely Five O'Clock Spoons that is a series of floral designs. Each spoon is different. I can see this being handy when ladies were having coffee in that all the spoons were the same piece and pattern, but just a little different in design, as not to be confused.
