Technical Drawing For Bristol 401

Good Morning,

I am new to the site and I am looking for help, I am looking for Technical drawings of the Bristol 401 as I wish to make this as a picture.

I have been in Contact with Douglas Newton who had illustrated the other drawings. He unfortunately could not help as he had not enough interest from the Bristol Owners to do these drawings.

Is there anyone who could help me in my plight.

Thanks.
