Bonneville double hung sash locks

Question

Hello, I wonder if you can help. I have a number of wood double hung windows from about 10 - 15 years ago. A sash lock has broken, upper sash will not stay properly closed.

i have looked at hundreds of sash locks online .... none of them this one! It is heavily recessed into the wood of the sash, so I can't just install a different one. Is this type still available anywhere? It has a number stamped on the handle: 41328 1

thanks for any info you can provide. Paul

Hello,

Unfortunately, we do not carry a suitable replacement for the sash lock shown in your photos. Our closest options would be the 90-320 used for wood windows but ours installs with screws through the back of the lock, while yours appears to install from the bottom. I'm sorry we won't be able to offer a closer match but please let us know if you have any other hardware questions. Thanks for posting.
