Need info for Hewlett Packard Oscilloscope 1740A

Does anyone know where I can obtain info on the obsolete HP 1740A Oscilloscope? I have the HP manuals but components such as transistors often have the HP component number rather than the actual part number. Also, a source of spare parts would be useful since some are HP specials and not now available.
