Norris Planes: Production Dates

Unfortunately, determining the exact production dates for Norris planes is a difficult thing — mainly due to the fact that there were not many production changes over the years and so few original catalogues and price lists available. In fact as far as I know there are really only three main sources that I have access to, the 1908 price list, the 1914 catalogue and the 1928 catalogue. There are other price lists out there, including one from the mid 1930’s and one in the 1940’s, but I do not have access to them.

There are also a number of catalogues from resellers, such as Buck & Ryan and others, who offered Norris planes at various stages. This can further muddy the waters as it is not known exactly if the planes were still in production or whether they were merely remaindered stock.

With this in mind I ask you to consider the following list of production dates with a grain of salt.
