I am trying to find documents describing its (Wilson) Pre-selective Gearbox. At present I have found 2 documents on the internet:-
- LUBRICATION and CARE of the WILSON SELF-SELECTING SELF-CHANGING GEARBOX
- INSTRUCTION BOOK of the E. N. V. PRE-SELECTIVE G E A R B O X
Does anyone know of any other documents on this subject which are available - free or otherwise?
See below for pictures of my gearbox.
