It’s from a trunk lock. Those are the dates for Conrad Liebrich’s patents for the lock and subsequent improvements to it. The original patent was granted as “Trunk Lock” on 2nd May 1854 and as “Trunk Lock Hasp”, extended for 7 years on 1st Noivember 1870, as well as “Improvements in Hasps for Trunk Locks” on 26th February 1867.
