[550] Vintage American 600 padlock 

A big thanks to Paracentric for sending in this beautiful vintage American series 600 for my round body padlock collection.
I did try again to remove the two retaining pins on plug but failed.
These are great padlocks. Yes, obviously they can be picked by anyone skilled enough to do so but we all know locks are more likely to be cut or in some way destructively removed and these are built tough.
In my opinion, more often than not, the lock itself is not the weakest point.
It's usually the hasp, hinges, windows etc.
Don't be the easy target. Stay safe out there.
