Culmak Works in London registered their first patent for shaving brushes in 1933, and continued to produce their wares for a few decades, they are pretty awsome shaving brushes as most of them are small to very small, and the majority of them fitted nicely into the old, aluminium shaving brush tubes/containers.
This is a fine specimen; badge in place, nice condition on the handle, and original boar knot, a keeper for sure!
This brush stands 94 mm tall with a diameter of 34 mm on the base. The knot is a 20 mm boar, and is set at 48 mm.
