finally got hold of my aunts Moulton. Been after it for at least 35 years , maybe more. Still very original but needs work. Main problem is shifting stem. Don't know how long it is or how long the fork column is but it isn't moving. don't want to damage anything inside. Been soaking in all sorts of stuff for months to no avail. Heat isn't an option as the paint is to good. Any suggestions or a link to a diagram of the front end. Tried the Moulton owners but very hard to plough through their site/forum.
