Ive been scanning this manual for someone so I thought I may as well stick a link up of the contents. Its dated 1992 and ideal for the 348 and 512TR but I'm sure a lot of the components listed are used on other models either side of the date. The diagram section is good for identification. Names the original manufactures and their part numbers too. Help yourselves to the pics if you haven't already got the manual. Its all good info.
