介绍（中）	基于Johannes Zumpe的简单方形钢琴设计，这款优雅的乐器融合了多项创新。通过在响板下方延伸按键的设计，可以实现5-1/2八度的扩展罗盘。调音针已经从右侧移到了方便的位置，在那里，调音针非常拥挤，而且远离最低音键。这架钢琴没有阻尼器控制；当主盖面板关闭时，踏板打开响板上的盖片。1785年左右，布罗德伍德用踏板取代了手动挡块。到19世纪90年代，他的公司每年生产约400平方米和100个孙子技术说明：长方形的箱子和盖子，带有红木（？）面板，与梧桐木或缎子木接壤，由细黄杨木和乌木条纹以及更宽的紫木线条隔开；在4个方形的锥形腿上，支撑着一个前凹的搁板；FF-c4（68个音符）键盘，带有象牙自然色，带有模制正面和乌木凹凸；1个扁平的木踏板抬起盖子的右前盖以膨胀；沿着脊柱的未穿孔的长圆形调音针；英制单动式，带黄铜欠电流（无阻尼器控制）；整个乐器都是双弦的，最低的12个音符用铜缠绕在黄铜上；原装真皮锤套。
介绍（英）	Based on the design of Johannes Zumpe for a simple square piano design, this elegant instrument incorporates several innovations. An expanded compass of 5-1/2 octaves is possible by a design that has keys extend under the soundboard. Tuning pins have moved from the right side, where they were crowded and far from the lowest key to a convenient arrangement along the back. This piano has no damper control; the pedal opens the lid flap over the soundboard when the main lid panel is closed. Broadwood replaced hand stops with pedals by around 1785. By the 1790s his firm was making about 400 squares and 100 grands annually. Technical description: Rectangular case and lid with mahogany (?) panels bordered with sycamore or satinwood separated by fine boxwood and ebony striping and a broader line of purple wood; on 4 square, tapered legs supporting a shelf with concave front; FF-c4 (68 note) keyboard with ivory naturals with molded fronts and ebony accidentals; 1 flat wood pedal raises right front flap of lid for swell; unpierced oblong tuning pins along spine; English single action with brass underdampers (no damper control); double-strung throughout, lowest 12 notes wound with copper over brass; original leather hammer coverings.
