DOES ANYONE HAVE ANY INFORMATION AS TO WHAT TYPE OF PADLOCK THIS IS? IT IS KIND OF WEIRD LOOKING. I FOUND IT IN AN OLD, PLOWED, FIELD THAT WAS A FAIRGROUNDS UNTIL 1910. IT APPEARS THAT A FRONT SWIVEL COVER IS MISSING.
I have pics of the keys that fit this somewhere in my books. Ive seen it called a railroad lock. This is not the same padlock but you get an idea of the chain that connects on the bottom. Key cover also missing.
Here are some pics from my books, while not an exact match. They are made by different manufacturers and date late 1800's. All I see is a number 3 on your shackle, look closely maybe something else..
