Looking for an Andersen casement lock, appears to be from roughly the 70's.

Thank you for your continued patience in this matter. Unfortunately, after extensive research, we have been unable to find a replacement for this lock. We believe it has been discontinued and is no longer available. The only thing I can think to suggest is may be our 38-144 with our 38-276 and 38-277 keepers. Check them out and see what you think.
