A large and heavy antique key. One can only imagine the heavy, imposing door this must once have opened. Certainly 19th Century and quite possibly older. I have left the rust intact and just brushed off the looser particles.
This key measures a little over 7 inches in length (18.5cm) and weighs 10.5 ounces (300 grams).
In the past we in the UK used to 'give the key of the door' as a 21st Birthday gift. Nowadays the age of majority is 18 and ownership of the key to the family home is normally acquired at a much younger age. However, for a traditional family, this would be a great 21st Birthday gift.
