Should be either an LDE/I-5800 or LDE/I-7800. I think 5800, so higher models at the time were the 7800, 8800, and 9800.
5800 is standard capacity, 5-temp variable thermostat, Reg & Perm Press thermostatic auto-dry cycles, and timed.
7800 is super-capacity with the "bump-outs" on the rear bulkhead and drum ... and I think had "Supreme" on the console which this one does not.
