Gosh ....that's amazing that it's taken four and a half years for you to find these... . It must have been quite disheartening for those restorers especially after the amount of work that has been done to have not heard anything for so long .. so I'm glad that you found the restores and was able to say thank you ... All sorts of circumstances can occur in the real world that prevent someone coming back to answer a query or acknowledge an answer and it's easy to presume that someone has either become ill or forgot or was a novice maybe in navigating around an internet Forum ...whatever the reason I am really pleased that you found these after all that time and was able to thank those who worked on your photo.
