Old Padlock Help

[joer0952]

Hello, I purchased an old antique chest and it came with what appears to be an old railroad padlock. The lock was not original to the chest that supposedly came off of a British ship. The padlock came with a key and I was trying to find a way to get a 2nd key but I don't even know where to begin and I was wondering if someone here could help me. Below are pictures of the old lock and the key that it came with the padlock has the number 1964 stamped on the shackle and the only thing stamped on the key is adlake (both stamps can be seen in the pictures). Thanks in advance for any help
