I am trying to find a lock and key for my wonderful boyfriend who has a lock picking hobby. He showed me a picture of a lock he wanted but all I recall is it is a replica of either 1700s or 1800s and the key looked similar to the picture.

I don’t want to ask him to show me again because I want it to be a surprise. My boyfriend is the kindest most giving individual I have ever known and I want to do something to show how much I love and appreciate him. Can anyone help me narrow down what type of lock and key I am looking for? Thank you so much!
