During an inspection in this house which was built in 1913, we found this outlet that is a 3 prong with an open ground. I pulled it out to replace it with a 2 prong but am not sure what wires go where. I believe the top right wire on the socket is black, so there's black, white and red. I also think there's one other 3 prong socket on that wall that I'm guessing this runs to. I had a handyman with some electrical experience look at it but he wasn't quite sure so hopefully, someone can shed some light on how to do this. Thanks.
