Metropolitan - London Grand Rank - Apron Badge (Craft Undress)
This hand-embroidered London Grand Rank Badge features the square on which is appended the 47th proposition of Euclid. This is the symbol of a Past Master of a lodge, but in this context, in dark blue, it signifies the authority of an experienced Freemason. The undress badge, like the apron to which it is attached, is in Dark Blue, showing the rank of the wearer. Undress Regalia is to be worn for normal Lodge meetings and events.
