Want to put the original sink back in my house which was my Great Grandfathers. House was built in 1912 and the old cast sink is stamped 6-14-12. The faucet handles look like a plus sign with a ball on each tip. These have a porcieln center marked H and C. I do believe that I need to remove the porcieln tops to get to the screw which holds the handles on. I can not even so much as get a razor blade started under the edge of them. The seats are good,but the rubber top-side is rotted and certain to leak. First time user of this site and think I will enjoy it. TIA
