Michael, you have come to the right place. If you send your e mail details to the club e mail address vhgmc@btinternet.com I can let you know about obtaining manual and clutch plates. If you have the machine serial number I can also look it up in the factory records and date it for you.
Once it is scanned I will have it saved for the future. If you send your e mail address to the VHGMC e mail address vhgmc@btinternet.com I will pick it up.
