Old Junkunc Bros. American Lock Co. padlock

I just got an old Junkunc Bros. padlock which I like very much. I only found a few pictures and one video on a padlock like this. I already started cleaning it and with cleaning I just mean removing old dirt and grease. I will leave them like they are and not polish anything! (Would never do that). This might be one of the first mass produced padlocks with ball bearing locking mechanism or am I’m wrong with that guess? I would like to know how old this padlock might be, the locking mechanism is very interesting (ball bearings with craters in shackle like on my Anchor Las) seems to be a wafer if I am not wrong. There is also a number stamped in at the top. Does anyone know what it means? Las thing would be the screw on the opening side of the shackle, any idea what this might be for? Can you maybe disassemble the padlock? I do not want to break anything therefore I am careful on this one. Thanks for your help!

Thank you for that information BBE. We have been puzzling over if they were the first or not. I would love to have one of those shirts (rofl)

Thanks for all the information BBE 🙂

I tried to fit the core with only one spring and as you said it is not that efficient then. I prefer it with two of those v springs.

While putting the padlock back together I have recognised that the nail has to aimed at the bottom, just in case anyone wonders why. The spring fits perfectly into a deep hole at the shackle so it won’t twist there. The nail will then prevent the spring from twisting at the bottom of the hole where the shackle fits in.
