I have one of these too. I got mine from an auction site and I believe it is made in china/india and is mass produced. it is a great heavy lock, and gets alot of conversation because of it’s size. I am letting mine sit out to collect some patina, and will probably never sell it.
A note.. My key is a number 5. Yours is cut different, and it is nice to see that they are not ALL keyed alike. Just an observation.
