介绍（中）	虽然这架钢琴是在荷兰制造的，但它具有许多英国钢琴设计的元素。该机制是英国动作，采用1786年在伦敦获得专利的中间杠杆。此外，前 15 根弦由位于音板背面缝隙下方的锤子敲击;此功能是另一项英文创新，允许外壳容纳扩展键盘。该乐器装在一个小型桃花心木箱中，支架两侧配有手柄和拱形前部，为演奏者的膝盖留出空间来操作膝盖杠杆以抬起阻尼器。技术描述：方形钢琴桃花心木贴面盒，黑色镶嵌条纹，缎木饰面弯曲铭牌，镶嵌椭圆形铭牌，末端华丽镀金提手，带4个方形锥形腿的桌面支架; 未穿孔的调音销; 象牙色天然，带模制键前部，乌木意外，无法操作的膝盖杠杆，可能通过抬起钥匙杆的后部来抬高阻尼器，指南针 C-f4（66 键）;英式双动，中间杠杆，无擒纵机构;连接到钥匙杆背面的电线穿过挂钩导轨并带有小布垫阻尼器;单串通体，底部6个音符缠绕;键杆 D#3-F4 延伸到音板下方，锤子敲击音板后边缘的开口。（L. 利宾 76 年 8 月 4 日。
介绍（英）	Though this piano was built in the Netherlands, it features many elements of English piano design. The mechanism is an English action and employs an intermediate lever of a type patented in London in 1786. Additionally, the top 15 strings are struck by hammers located beneath a gap at the back of the soundboard; this feature, another English innovation, allows the case to accomodate an extended keyboard. The instrument is housed in a small, mahogany case, and the stand is furnished with handles on the sides and an arched front to leave room for the player's knees to operate a knee lever to lift the dampers. Technical description: Square piano mahogany veneer case with black inlaid striping, curved nameboard veneered with satinwood, inlaid oval nameplate, ornate gilt carrying handles at ends, table stand with 4 square, tapered legs; unpierced tuning pins; ivory naturals with molded key fronts, ebony accidentals, inoperable knee lever, possibly to raise dampers by lifting rear of key levers, compass C-f4 (66 keys); English double action, intermediate lever with no escapement; wires connected to backs of key levers pass through hitchpin rail and bear small cloth-padded dampers; single strung throughout, bottom 6 notes wound; key levers d#3-f4 extend beneath soundboard, hammers strike through opening at rear edge of soundboard.
