Possible typo? "Diagram Index for wagons was first prepared circa 1905, followed by a similar index for wagons around 1910"--[[User:Patrick Hearn|Patrick Hearn]] ([[User talk:Patrick Hearn|talk]]) 19:31, 18 October 2022 (UTC)
:Yes, the wagon index was 1905 and the carriage index followed in 1910 (from Atkins ''et al'' (2013), "On using the book"). --[[User:Robin|Robin]] ([[User talk:Robin|talk]]) 13:58, 21 October 2022 (UTC)
