Message inside a rimlock

A while back, as I was opening up the interior of the rimlocks to check them inside, I stumbled across a hand carved message in the cast iron plate! Actually, I hadn't even noticed it at the time, I had taken a photo of everything as my standard procedure is and only upon reviewing the photo did I notice the writing!

How cool!

I'm not too sure what it says, but the second line reads May 20, 1904
