Dąbrowski has an unidentified “Masonic Symbols”, see below. It looks somewhat alchemical. Perhaps it is from the Gold- und Rosenkreuzer or some similar group. I don’t know in which degree this image is featured and if there are other systems or degrees with this symbol, but it could be a variety to the hammer and chisel of the first “craft” degree.
Dąbrowski P. 164 “Masonic Symbols”. Year and designer unknown
