Overall: AGF on the offline sources, but the sourcing frequency is adequate and the online sources are acceptable. I might add to the hook that the device was invented in 1872, and perhaps that it continued to be used through the 20th century, as I think that's an interesting detail. There's a freely-licensed diagram that could be used as a hook image, although the small text labels may be undesirable at 120px. GorillaWarfare (she/her • talk) 17:14, 1 July 2024 (UTC)
