This splendid Broadwood is number 37518, and an advanced piano for its time.
We believe that 'Patent' refers to the new check action. When properly adjusted, this enables better regulation, and significantly improves the playing experience.
In these pianos with a check action, removal of the action for maintenance does require an extra step, and if I am correct, the brass catches to enable this can just be seen in the pictures above and below.
In any case, we can see the benefits of recent careful restoration; this one is very clean and tidy. And I just love that beautiful black and gold swirly enamel!
This was one of the last of the Broadwood squares to employ the double bridge, patented for grands in the 1890s. This enables the first of the steel strings to be longer than the last of the brass, thus preserving more equal relative tension: brass is heavier than steel, but not as strong. Very soon, this elegant and acoustically-correct refinement gave way to heavier steel strings and monochord overspun basses. It is perhaps my job to be a professional misery, and I would just comment that four pairs of the brass bass strings have been replaced with steel. They work, of course, but it would be simple enough, and a kind thing, to re-instate brass (Happy to help with this finishing-touch).
this fine piano is in Wellington, Somerset; the price is £1,000. Please contact Tim Williams T.Williams@wellington-school.org.uk
