WTB Glock 19 stock rear sight

Somewhere in the course of moving, the rear sight came off my Glock 19. I know there are a ton of folks who have replaced their rear sight with after-market upgrades - anyone still have their factory sight sitting around? From what I can tell, it's the same part number for most models of Glock, so it doesn't necessarily need to be from a 19.

Let me know what you have, and how much you want for it.

Thanks.
