Sargent #6408 Shaw Patent Prototype
The #6408 Sargent is one of the rarest hand planes you’ll need to find as a Sargent Collector. Other than this one, I’ve not seen another for sale, and I know of only 3 in private collections.
This plane is in this post, https://www.timetestedtools.net/2016/02/13/the-elusive-6408-sargent/
This plane is also the actual plane featured in “THE SARGENT HAND PLANE REFERENCE GUIDE FOR COLLECTORS & WOODWORKERS – SECOND EDITION” also available on amazon.
It’s the plane shown on the back cover and on page 42.
In 1906, John H. Shaw patented a frog adjustment mechanism that allowed the frog to be adjusted without removing the iron. This patent was then manufactured as the Sargent’s #7 through #24. These were advertised from 1910 to 1918.
The Sargent Shaw patent was listed first in the 1910 catalog but was manufactured from approximately 1906 – 1918.
Type 1 and 2 Shaw patent planes are given the #6408 designation and were produced in only that size. Type 3 planes include all sizes, #7-#24. Some of the features found on the earlier types 1 and 2 also appear on some of the later planes.
