Arcadia Sliding window lock from the 1950's

I'm afraid we won't be able to supply anything from this window. It's just too old. It's also huge, as far as sliding windows go. The lock and pull used for it now looks like hardware for a sliding patio glass door.

With that in mind, I recommend our 82-005. This is a surface mount handle set used for sliding glass doors, but it may potentially work for your window, as well. It has its own self contained mortise lock that doesn't rely on any mechanism already installed in the door (or window, in this case), which makes it very versatile. Look it over and let me know what you think.
