There are lock collectors that go nuts over antique pushkey or 6 lever padlocks with unique names. There are literally hundreds of them, so I’m not surprised you can’t find the exact one you have. I would estimate your antique push-key or 6 lever lock is worth between $50-400 dollars:

I could be way off, it could be worth much more, but I’m not an expert on 6 lever locks. There are a lot of collectors, so hopefully someone else will comment on your padlock.
