One of these.
I wouldn't dare put one of those in my wallet!
Last Saturday the wife had a little raid of it and I can't even afford a 6 pack now.

I have about 10 leaf shutter lenses for medium format here from '50s to '70s
I have tested most of them over their time steps and they are generally OK.

Here is test record of an RB67 Mamiya Sekor C 1:4.5 50mm times at axis and edge(corner) at various apertures.
It is about 25% slow so I call it OK as that is only a fraction of a stop, and in the good direction for C41.

I think leaf shutters get more problems from lack of use than from use.
I think 20000 is conservative.
There is one old shutter here from a production camera that has a lot of wear on the cocking lever spindle but is otherwise OK with times "in spec"
