We have added new graph paper specifically suited for Kromer 14a safe locks to our Safe Manipulation Graph Paper page in the Tools section. The Kromer 14a is a unique safe combination lock. Rather than numbers, the dial used letters (upper and lower case).
Kromer was a leading safe lock manufacturer in Germany from the early 20th century up until the 1980s. They had a very good reputation because of their Protector lock, which was the only lock certified by the German national bank for use on their safes for many decades. Kromer also sold Novum locks across Europe, many to the U.K. who equipped them on Tann safes.
Special thanks to Martin Hewitt for putting this together for us.
