Nancy, my Davis serial # is 2424236. I'm sure it's not been changed out because the lady I bought it from knew the family and they said it had been their mothers forever and after she died they put it in the basement and it had never been touched. And it was in there so tight it took us forever to get it loosened up so it would move, I won't say slide because it still doesn't slide without being coaxed with a screwdriver and hand heel.
