Hello I am looking for information on a lock I have

[AnitaJ]

I have a very old padlock type lock. Not sure of age or even maker I has 4 different keys with the lock and they each have to be used in a certain order to open the lock. I am seeking some information as far as who made this lock and approximate age. Thank you to any one who could be of help.

That is what is known as a trick lock, or more specifically, a four trick lock. The trick of course is in knowing which key must be used first. Some are German, some are Russian. They sell on Ebay from time to time, you can search there for price reference.
