KA PORTABLE DW KDS-58
Morgantown West Virgina ?, being this is a portable it is likely is much better shape than most 18 built-ins. These can be easily converted to a BI DW if that is what you need, one slight difference is that the portable version has different very long door counterbalance springs that eventually break and are NLA, good news is the extra long GE DW springs from their early 1980s machines are are much better springs than KA used.
