I recently bought used - a stacked washer/dryer combination. I don't know anything about their age or original cost. I need both operationing manuels. BOTH ARE 220V. i NEED THE MANUELS AS I clicked above but the dating and estimates of original costs would be appreciated also and whatever else might be of historical merit on these models. I have two sets of numbers off each. T6500BOUC & M6120BIUC the corresponding other set of numbers on each one is E-NR WTA3500UC / 10FD8005 19631 5059105UC6 and the other is E-NW WFK2401UC / 01 FD 8005 34025
