Chas. Salewsky Summit Farm Dairy Wisconsin

One pint milk bottle embossed on the front, "ONE PINT LIQUID SUMMIT FARM DAIRY CHAS. SALEWSKY" The bottle also is embossed with a big square on the base with an S in the middle and the number 42. On the heel it is embossed, "SEALED 1-14-14 MTC B REGISTERED"

I know nothing about milk bottles in regard to determining age. If someone can tell me how to asses them I would be grateful!

This near antique bottle has the very distinct honor of being one of very few bottles I intend to keep that aren't Wisconsin pre Hutchinson soda bottles. Summit is the small town at the west end of Waukesha County, Wisconsin where my wife and I recently built our home. I would be interested in any other examples. As far as I know these milks are the only bottles from Summit.
