noytd, I keep thinking that the shield above the door may yield some clues.
I have no knowledge of such things, but do you think it might be worth rescanning it?
The experts may be able to advise settings etc and how to do this to get the best results. I know that some have programmes to enhance photos to bring out more detail, so this may be worth a try.

I note that the shield, or parts of it, appears in a few photos, so I am wondering if it might be worth scanning even those which don't show the entire shield? Photo 2 for example appears to be a bit sharper though the top part of the shield is cut off.
