Incombustible Bauche safe

[Craig Sitch]

Hi gang,
Total newbie here, recently we were gifted an old Bauche safe. It has no keys, and its not in the best condition, but we restore a lot of old things, so we would love to try and give this a go too.
Firstly, we would like to know as much about this sort of safe as possible, so we can then figure out a plan of how best to get into it. Googling came up with a few pictures of similar safes, but no dating. I've emailled Gunnebo, the company that now owns Fichet-Bauche, as well as a local locksmith, but I thought you folks would probably be more help. :)
Here are a couple of pictures of it.
Thanks in advance
Craig
