Need help identifying old lock

[05Esky]

Hey everyone, I found this lock a river in central florida not too far from the inlet and needed help identifying a time period and more about it. From what I found I think its a Slaymaker due to the logo but cant find any slaymaker logo that matches the design around it, only the "S" is the same or very similar. Any help would be awesome...

I searched for nearly an hour and found nothing. Maybe an English/UK firm.

Probably a railroad padlock, since it has a hole in the bottom for a chain to attach. Any railroads in your area that begin with the letter "S"?

Here's a list of current and obsolete railroads in Florida. Maybe the padlock came from one of them:

The padlock is a Slaymaker lock. Cant help with the date though. In the style of locks from the 1890's - 1920's. If it would have been used by a RR, it most likely would be stamped somewhere on it.
