I have a MK1 Spitfire manual which has been signed by Air Commodore A Washington Morris printed in 1939. It has details, specifications and illustrations of this model and is rare from what i have found out. I am interested to know the value of this family inheritance for insurance purposes. There is very little info on the net unless i am just not looking in the right places. I can email JPEG photos if anyone can offer some advice. Can anyone help?
