Dąbrowski has an unidentified “American Masonic Symbols”, see below. The triangle with 12 candles seems to refer to the twelve apostles and is (possibly among others) part of the Knight Templar degrees.
It can also be seen on a painting that (according to the same author) can be found in the National Museum of Scotland. There the candles are clearer and the skull and crossbones in the middle may point towards certain degrees.
Millar says of the image above that it: “is typical of the imaginary of the Knight Templar degree.” The jewel also comes from Millar.
There is an odd similarity to the triangular way the Menorah is displayed on several of the tracing boards in the Kloss/von Löwen collection, like the one below.
