Well, here are a couple of turn of the century flasks. not the oldest bottles Ive dug, but nice to look at, they are embossed: Quaker Maid Whiskey (S & H CO. monogram)
These flasks are blown, and not machine made, they do have tooled tops. Also I would think the same about the SC & H monogram, but there is an "o" in the middle of the letter " h ". chris
