Purchaced a 1957 home, latch for small window in laundry room crumbled when attempted to use, need replacement. Says "KELLER" on top. Half circle type that you rotate to lock/unlock.

Hello,
Take a look at another customer's inquiry for a Keller sash lock here and see if you could adapt either the 90-005 or 90-009 that we recommended to work for you. Thanks for posting!
