I'm skeptical that the photo shows any builder's production or even semi-production yacht, like Burger. (For one thing, every Burger I've ever noticed had a flush deckline).
My bet is that it's a custom yacht off the board of some high-end designer like M. Rosenblatt & Son, whose designs were built wherever their owners chose. That was a thing among the wealthy in the 1950s, which looks to be the vintage of this vessel. But if that's so, I also think it's been modified. Those two semi-raked fashion boards just aft of amidships don't look original - they seem inconsistent with the rest of the yacht.
