ATM KEY NCR5870 (FFE3)

[MacGyver1100101]

Hello, I lost my last FFE3 key for NCR5870 ATM today and now I need a new one. I have a lot of matching key blanks here. Can someone give me me exactly the millimeters, where there is the cut in the key? It is very easy because this key has only one cut. Or maybe a picture with 100%, 1/1 scanned. No photo with camera or handy/mobile please. I will not know what size it is. Please have a look at my attachment. With a picture or the exactly millimeters i can help myself. Please help me.
