milner 212, missing key

Hallo.
Just a quistion about a Milner 212. missing the key. doors is open.
Where can I get a key and about what price ?

what can i do - bring it to a locksmith , or oder from milner serienumber or unscrew lock from inside ?

what age is the safe ? any value ?
don`t have the serialnumber yet.

thank for helping -

Milners don’t exist anymore and even when they did they could not cut keys from serial numbers.

If you take the lock to a good locksmith he will be able to make keys for you.

If you find the safe serial number it should be possible to date it.
