701078 Breast drill, before 17th century (fruitwood, brass & iron) by German School; length: 60.3 cm; David Russell Collection; (add.info.: This bevel-gear breast drill combines elegance and function. The fine-quality turning in the neck and pad is matched by the craftsmanship of the carved gears, by the elegance of the brass strengthening plates, and by the engineering of the spring-loaded button in the bevelled shoe of the tang. There are three holes, apparently for lubricating the bearing, and on the handle arm there is a possible touch mark. ); out of copyright.
