Periodic Table formulations from the year 1905:

1905   Werner's Arrangement
1905   Gooch & Walker Periodic Table
1905   Gooch & Walker's Periodic System of The Elements
1905   Gooch & Walker's Primary, Secondary, and Tertiary Series of Elements


1905

Werner's Arrangement

Werner's Arrangement is the first modern looking PT formulation. It appeared before the structure of the atom was known, before the importance of atomic number was recognised and before quantum mechanics had been developed.

Berichte der Deutschen Chemischen Gesellschaft (1905), 38, 914-21 and J. Chem. Soc., Abstr. 88, II, 308-9 1905:

From Quam & Quam's 1934 review paper.pdf

Gooch & Walker's Periodic System of The Elements

From a 1905 textbook by Gooch & Walker: Outlines of Inorganic Chemistry (see the Google Books scanned version pp273) comes an early 'right-step' periodic table. The formulation was reproduced in a 1917 textbook (lower image).

Gooch & Walker's Primary, Secondary, and Tertiary Series of Elements

This three dimensional formulation – clearly developed from the Crookes' vis generatrix model – is given a 1905 textbook by Gooch & Walker: Outlines of Inorganic Chemistry (see the Google Books scanned version pp273).

"The arrangement of the elements in three series of eight groups each may be represented by a model in which large and small wooden balls, on a spiral wire, represent the common and rare elements respectively; those balls falling in the same vertical column representing elements in the same groups":
