Hopper 300 window fastener

A contractor from Annapolis, MD says:
I need the left & right fasteners for my Hopper 300 window. It is a 32"x19". These are the numbers on it, 3219L30, also 16162182.7.1 and 2557. Any help would be great! Thanks

I'm afraid I wasn't able to cross-reference those numbers to anything. Can you show me a picture of the part in question?
