Talk:Preselector gearbox
From Wikipedia, the free encyclopedia
[edit] Invented in 1928?
A succession of edits have resulted in the first paragraph saying: "It was originally invented... in 1928... and was first used in World War I tanks."
Does anyone know the correct dates? Perhaps Wilson used them in World War I tanks and then patented the gearbox in 1928. But this is just a guess as I'm not familiar with these details. Can anyone help? Adrian Robson 11:13, 11 October 2006 (UTC)
