Replacement sash window top left & right platsic latches

I did not find any marking or number on this latch & unfortunately & I do not know what brand of windows the are. They were in the house when we purchased the house.

I would like to purchase the same style if at all possible to mach the other windows. I did look on the internet to find the same style but was not successful.

Hopefully you can help !!!!


Thank You
