sash lock replacement

A contractor from Glenside PA says:
I do not see any sash locks online that match this type. The upper sash portion has screws entering horizontally into the sash, and the piece is mortised into the sash. I need a set, or two complete locks (sweep and latch).

Hello there. How does our 90-309 Sweep Lock compare? See the diagram below. Note that we also sell a version with an opposite-handed orientation, the 90-308.
