Babbage, Charles

This series comprises 17 tracings of the original design drawings in Series A for Difference Engine No. 2.

However tracings BAB B/18 and BAB B/19 refer to both the Analytical and Difference Engines. The relevant original design drawings and tracings are cross referenced to each other on both drawing and tracing. Some of the tracings were made from the original drawings to show more clearly certain aspects of the machine by eliminating overlaid detail.

The drawings were not dated, but probable dates have been indicated in the date fields, to reflect the period of time when the original drawings were made.
