I am impressed with Bruce's work so far. It should be book-marked on any Triumph owner's computer.

I have compiled parts books from 1963 until 1982 into one book. I have been working on it, off-and-on, for 35 years. There must be at least 1,000 hours in the project. That only includes the unit 650-750 models. This leaves the 200, 250, 350-500 (both unit and non-unit models), 650 non-unit and triples left to do.

To further confuse things changes were made on the production floor that were not documented on drawings. Also changes were made on drawings that were never implemented on the production floor. This was especially a problem around the years where engineer was were made at Umberslade Hall that never made it to the Triumph production.
