/zink/ for "sink"--How widespread?

[GSCole]

Seem to recall a discussion of the use of 'zinc' for sink, on this list,
several years ago.

Growing up in northern Delaware, we (my family) called the large,
angular, side-by-side washtubs zincs.  The single tub was a zinc.  They
had a whited-lead look to them.  I was told that the metal in them was
zinc.  Other large tubs, not made of a similar metal, were merely tubs.
Smaller ones, not used in a laundry area, were sinks.
