Tilt window latch patent #5.139.291

Good morning!

My wife recently ordered window latches, and it looks like we got the wrong ones. 

Here is what we need (pictured in 4 photos): 18mm x 72mm x 7 mm

Here is what we bought: 17 mm x 68mm x 10mm

Hopefully you have them...otherwise a window will probably jump out and attack us! :-)

Thank you!
