In this display case we can see a set of standards of weight consisting of:

• 2 arrobas;
• 1 arroba;
• 1/2 arroba;
• 8 arráteis;
• 4 arráteis;
• 2 arráteis;
• 1 arrátel;
• 1/2 arrátel;
• 1 quarta;
• 2 onças;
• 1 onça;
• 4 oitavas.

The decoration could vary, depending on the size and weight of the standard. On the larger pieces, we often see the Coat of Arms of Portugal – a Latin shield with 7 castles on a stripe around the edge, topped by a closed royal crown and flanked by a crown of laurel, as well as an armillary sphere.

The smaller pieces, namely the eight arráteis and below, were decorated differently, as we can see: the Insignias of the Brotherhood, in another framework – divided French shield, the first section (left) being the coat of arms of Portugal and the second section (right) divided horizontally: on top, the ship, which is the symbol of the city of Lisbon and bellow, the mitre and sceptre. All this overlaid on the armillary sphere which is topped by a closed royal crown.
