Humphrys, Tennant supplied triple-expansion machinery to the Blakes and engines or boilers to many other major Victorian warships. Its work included the 1875 HMS Dreadnought, HMS Victoria, Renown, Sans Pareil, and Trafalgar. The firm was one of the era's leading marine-engineering specialists, but it did not secure a place in the shift toward turbine propulsion and disappeared in 1907. Its peers included Maudslay, Sons and Field and John Penn and Sons in a once-competitive British supplier base. Sustained demand for orders among several viable firms might have accelerated the Royal Navy's adoption of higher-pressure machinery. Competition creates technical pressure only when a navy buys enough equipment to keep multiple expert suppliers in the field.

Marine-engineering competition behind the Blake class
The Blake machinery leads into a wider lesson about specialist engine firms, turbine transition, and the value of a competitive supplier base.
