Dating record hand planes
I've converted some of the plane dating information found in Patrick Leach's Plane Type Study into an easy-to-use hypertext flowchart.Hopefully by answering a few questions about your plane you can determine which type it is.Unfortunately, many plane types share the same bed markings, so other features are also used in dating.
This approach doesn't guarantee that you'll date your plane correctly, as the flowchart can be thrown off by some hybrids.
Fortunately, many Woden bench planes retain their little-used original cutters which were marked in a specific way.
Hence it has also been possible to use cutters to assist with dating as three different types have been identified within the seven year period.
The flowchart starts by asking questions about the cast iron bed of your plane.
I've chosen the bed as a starting point because it has many easily identifiable markings, and it probably wasn't replaced that often.
