Oh, and most of the pin-tumbler American padlocks use the same cylinder, so what works for one should work for the rest... Keep trying.
The exceptions are the "hockey puck" (it's a variation of the standard cylinder), the ones that have cylinders for residential/commercial keys like Schlage C, etc., and the ones that accept Best-style SFIC. Sorry, I don't know the model numbers off the top of my head. It's been a few years since I've sold an American padlock...
