Might be a good idea to set up an open-ended thread with Mdina signatures and one photo of the actual item to go with it. Then an approximate time scale could be established for each type of signature . This might have been suggested before , so apologies if it has already been discussed .
Michael Hill says in his Michael Harris book "Most members of staff signed bases Mdina with family and friends sometimes joining in to help with large orders"
Cheers, Mike
