Ingersoll used to be a family owned British company but since acquired. They continue to make a small but highly regarded range of padlocks which are still manufactured in England. This is unconfirmed but our suspicion is that they were originally made for Military contract and now found their way into the civilian market as a high security padlock.

It is made from hardened steel which is graded in the UK and then finished in a dull nickel chrome plate to give it some weather resistance. This is important since imported steel from China can be of dubious quality. Strangely, the mechanism uses levers rather than disc or pins which have, in recent times, been seen as less secure. That said this lock used 10 levers which is twice the number required by UK insurance companies for lever padlocks. Can it be picked? Highly unlikely.

Body and shackle are hardened so forget about cutting it. Drilling? Well as you can see from the image below there is a Z shaped anti drill bar preventing that and then a keyway cover that slides over the top.


3 keys with every lock as standard. Note that you will not be able to easily get new copies made since the key blanks are not commonly stocked by high street locksmiths.
