Gen 1 MP40 question

[dent lizard]

My pin spacer doesn't look like the one online in the manual. I bought the MP40 used and it didn't have the label on it. It has 3 notches, does anyone know what glass thicknesses each one corresponds to? Largest = ? middle = ? and smallest = ?. Thanks in advance if anyone knows

Holding the spacer so that the "cut out" portion is on top.. Now flip it around and there is one pin in the dead bottom position. Now here are some pics I just took in that very orientation. You should now be able to easily figure out which setting you need. Hope this helps
