I have been sorting through a late uncle's belongings and have found a bundle of about 150 original sheets of engineering drawings for the Comper Swift C(LA)7. Of these, only four are blue print copies rather than original pencil drawings. On some sheets, there is just one drawing whereas on other sheets, a number of smaller drawing are squeezed on.
These drawing are in poor condition (water damage to one edge) but are clear and legible on the whole. They date from 1930 to 1934 from what I can tell.
A number of the drawings are amendments to earlier versions. Some of them have old pieces of sellotape on them which makes me think that these were the working drawings for when the Swifts were being built.
The drawing are fragile and I am reluctant to separate them all from one another as I may cause damage.
How important are these drawings and what would be best for the drawings (they do need TLC), for the Comper Swift community and for early 1930's aero-history ???
I look forward to reading your views and opinions (and answer any questions) to help me take the right step with this lovely piece of aeronautica.
