They were sent to me by Andres, who was originally from hungry and he tells me the older one this to Deice is about 50 to 60 years old.

He also says it hasn't been opened in 20 years.

The similar looking lock next to it is also made by L set.

It's called a SEC lock and this was purchased just a few months ago.

So what we're going to do is pick both of them open and see how they compare.

I'm going to start with the older lock.

This has a nice, wide open key way.

So I'm going to use a thick wiper insert in there and there's more than enough room to use a standard hook in 25 thousands.

Little click on one.

Nothing on to nothing on 34 Okay, five is binding.

Nice click out of five.

Back to the beginning, Click out of one that could have been a spool.

I felt a little bit a counter rotation on it.

Counter rotation on two got him set.

Definitely a spool.

Counter rotation on three.

And we got this open.

So two or three schools in there Not too bad a pick on the newer lock.

We can see.

It definitely has a tighter key way.

I'm going to use a smaller tension tool and probably moved down to the standard hook in 18 thousands.

Okay, Nothing on one might have gotten a little click on to Nothing on 34 is binding tightly.

Nice click out of four.

Five is binding.

Click there.

And we dropped into a false set back to number one.

Counter rotation.

Okay.

And I think we got number one set.

Definitely a school.

Nothing on two counter rotation on three.

There we go.

I think we have three set nothing on 445 Nothing on one.

I think maybe we didn't quite get three set No.

Three fields set.

Click out of four.

Click out of five.

There we go.

Okay.

So it's difficult to say if there's a significant difference.

Clearly, the newer one was trickier to pick.

I think the pinning was similar.

They both have a few schools, but the tighter Qiwei and tighter tolerances do make a difference, though I don't know how much of the tolerances have to do with the age of the two lakhs.

Either way, I don't think the difference is air going to slow down an experienced picker.

In any case, that's all I have for you today.
