Window lock keeper / strike plate

I am afraid I don't recognize this keeper at first glance. Can you show us the lock that works with it? That would help narrow things down. 

Thank you! I do recognize this lock. We in fact sell it, but not a keeper like yours. The two most common keepers used with this lock are the face mount 90-255 and the surface mount 90-254. Yours is kind of a strange combination of both, which I've never seen before.

Please give us a little more time to look into this and I'll get back to you ASAP!

Hello! Just giving you an update after the weekend. We're still trying to track these new keepers down and hope to have an answer for you soon. Please bear with us a little longer.
