Vintage One Pint Square Glass Milk Bottle

Vintage One Pint Square Milk Bottle. It has a S48 E and 58 stamped on the bottom, I believe the 58 is the date code for 1958 when the bottle was made. There is no label for what dairy company this is for. It has stamped along the bottom One Pint Liquid 586-13 Reg. The bottle is in fair condition and stands 7" tall
