As in historical on-readings ending in -ゐ, such as "ゆゐ" and "るゐ", most dictionaries do not have "すゐ", "つゐ", and "づゐ" as historical readings for 錘. According to historical data, the on-readings of 錘 are the modern "すい" and "つい", as well as "づい". However, the Dai Kanwa Jiten, has the -ゐ historical on-readings.
