I think this is a Worcestershire Sauce bottle, judging from the familiar looking cap. Anyway it is part of my hot sauce/condiment bottle collection. All of the knots are either Turk’s Heads or Turk’s Head variants done with an interweave.
The sloping shoulders give me fits sometimes, because the knots are all trying to crowd onto the smaller neck. My usual remedy, like here, is to knot on both sides first, and then let them fight it out for space. I can’t tell who won this melee, but the shoulders seem to at least have held their own.
