Sorry, but this place is so old (1973) the stickers are long gone! I know the home is four wire, since the electrician who serviced another home of the same model said he found a sticker that said:
120/240VAC
100Ampere
60Hz
"Connecting the green to the white wire in the home means you could energize the frame of the home." And the aluminum siding.
