Chatwood at the United Grand Lodge of England

Found another Chatwood vault door at the United Grand Lodge of England (Freemasons' Hall) in Great Queen Street in London. When you go to the rear part of the exhibition you pass the library. Directly before the library on the right hand side is this door. It is painted in brown to match the wooden doors. That means I could not find any serial number and the guy in the library could also not tell me anything about it. The lock is probably a double-bitted 10-lever lock with movable bolt stump. I see really many Chatwoods this year ...
