It was a huge animal, I think a power supply for a stone-age ITT answering machine/phone combo (1970ies I guess). 16V output and 2 2A fuses, either primary fuses for line/neutral or secondary fuses for +/-. Really huge and heavy. If you know the old Apple PowerBook 100 series wall warts, the same size but much heavier.
The one for the old Panasonic EasaPhone answering machines sold in Austria/Germany was similar. I once saw the US version of the same machine, much smaller power pack.
