I am afraid the chimney cap was already out of the top of the print before I came to scan it. I could have restored it in Photoshop as there must be other copper caps around in this collection to cut and paste in - but these are Dad's photos and I have tried not to do anything but try to improve the deteriorating colour and their sharpness.
