iwc WINDOW LOCK

Thanks for posting. Without a picture I cannot be certain, but I believe you might be referring to the old IWC lock another customer documented here. I am afraid we've never been able to find an exact match for this lock. Our 90-313 might work as a replacement, as it has similar offset mounting holes, but I cannot be certain it will work for you. Take a look and let us know what you think.
