This page includes each page of the ENV Type 75 Preselector Gearbox Instruction Manual.
Additional information will be found on the Main ENV gearbox page. This includes some information from the Manual but also information on adjustment and assembly of the Gearbox recieved by the writer from ENV in 1965.
To print these pages, right click and the "print target" option appears to give the clearest copy. However, this will depend on the printer you are using.
