Dąbrowski has an unidentified “Masonic Symbols”, see below. On the left and right you see two pedestals with men on them holding some sort of tools. The two Saints John perhaps? The one on the left appears to hold a St. Andrew’s cross though.
I don’t know in which degree this image is featured and if there are other systems or degrees with this symbol.
Dąbrowski p. 166 “Masonic Symbols”, it is the same design as the apron that Lafayette presented to Washington in 1870
