Historical maps of Devon

I am looking for digital versions of historical maps of Devon in the period 1600-1650. I am specifically looking for maps of parishes and manors within those parishes. I will be using these maps for research, so accuracy is key. It would be very helpful to have scans of hand-drawn maps from the era in question. I would like to see examples of your work before making a commitment. Please let me know if you have any questions. I am uploading a sample of a map which is the starting point and can form the basis of further development. Unfortunately no 'base' maps exist so the images need to be scanned in and the outlines digitally traced from the scans. I would also like to add simple graphics to highlight key characteristics of the parishes.
