Can't say I've ever seen one... but it *sounds* like it's just a cheap brass padlock that's got a relative no-name stamped on it.
If I had to guess (and given that it's 32mm), I'd speculate:
- 5 pins, rather small compared to a deadbolt
- probably got a few spools in there, as these seem to be unnaturally common in cheap padlocks these days
- likely requires a very gentle hand for picking and very little action (or movement) of the pins to set them.
Closest comparison I can think of to what I'm imagining would be a Garrison brass padlock (that can be seen at Canadian Tire, not that I think that will help you much
).
But it's purely speculation on my part. I'd try a short hook, lighten up on tension, and try and just gently brush the pins as opposed to consciously lifting them. When you feel a "give" in the plug, apply slightly more tension and then start to lift at each pin until you feel the plug pulling back. When you feel that, lift that pin a little harder while applying moderately firm tension. (What you're trying to do here is overcome a spool pin). You may need to repeat this process of beating the spool pin as needed.
...
Or, I could be completely wrong and I've just set you back two weeks of practice.
Happy picking!
