The Boston Pattern Brick Trowel

This rare 7 inch Disston Boston pattern brick trowel probably dates to the early 1900s. The 1918 Disston catalog shows this pattern on page 203, with the additional inscription "REG. US PAT. OFF." The lack of these words and the style of lettering dates this trowel to before 1918.

This trowel is also what's called "through tang, double ferrule" meaning the tang extends completely through the beech handle. The end of the tang goes through a hole in the ferrule and is peened over. Disston replaced the through tang, double ferrule design with the spiral tang, US Patent 1,524,633, January 27, 1925.
