Spad XIII drawings required for replica

Hi to all

…. I am looking into the possibility of building a full size and fully flying replica of the Spad XIII.

I am in contact with The Shuttleworth Collection regarding this project, but would really be grateful for any information on where I might obtain decent scale / manufacturer drawings.
Up to now I have been shown drawings for scale models !! — for 80-90% scale flying replica’s with steel frames —- but this is not what I am looking for.

It is my aim to construct a full size correct replica of this aircraft to museum quality and be fully flyable – by me !! ….. although some degree ( a great deal !! ) of leeway will be needed with the engine. But otherwise the aircraft will be constructed from the correct materials to the original scale.
I expect this will be a long project …. but it would be nice to get this off the ground with some accurate information to start with.

Any leads you may have will be much appreciated.

May all your landings be happy ones!!

Steve
