Was looking for some historic info on square grid bass layouts for accordions:
Joseph Galleazzi is showing what appears to be a square grid accordion bass system, in his 1893/1894 US patent US 517648 A (see figure 3):

His 1905 US patent ( US 795795 A) also includes some info on a bass mechanism and keyboard layouts. In figure 1 the bass buttons look to be in a square grid form layout.
Is figure 14 showing a reverse Stradella layout(?), not sure what is the top and the bottom in this figure 14:

In a 1990 book by Hubert Boone (Accordéon et basse-pieds en Belgique) is showing a 4 pages 1895 patent by Eduard Daoglio, Bruxelles, with a reverse (?) Stradella bass layout, using only one set of 12-rods or rotation axes. He claims a lightweight construction for a 36 bass system.
Its possible the development of the fisarmonica semidiatonica (often with square grid bass layout) had an influence on Belgian bass systems and Stradella bass layouts. Diatonic bisonoric accordions usually have square grid bass layouts.
