Bentley 3-1/2 & 4-1/4 Engineering Drawings on CD-ROM

Rolls-Royce factory microfiche documents were scanned onto CD-ROM (as high resolution TIF images at 20 dpi) and has scaled the size of the original drawings on to CD-ROM media for Windows PCs.  The quality of the images ranges from very good to poor and reflects the condition and age of the source materials.
