Antonio Favaro - "Sulla Elica Calcolatoria di Fuller con Cenni Storici Sopra gli Strumenti a Divisione Logaritmica"
Reale Istituto Veneto di Scienze, Lettere ed Arti - Venezia 1879
Italian

E' un saggio della massima importanza sulla storia dei regoli calcolatori. Ci non solo per il suo contenuto ma anche per la quantit impressionante di citazioni bibliografiche. Il lavoro citato tra l'altro molte volte da Cajori nel suo libro "History of the Logarithmic Slide Rule"

Antonio Favaro era il fratello di una mia bisnonna!

English

This is a very important essay on the slide rule history. That is true for his content and for the very impressive number of bibliographic quotations. This work was quoted many times from Cajori in his book "History of the Logarithmic Slide Rule"

Antonio Favaro was mine grandmothers brother!

Netsler Cross Reference
Un libretto di istruzioni del 1967 riporta la corrispondenza tra vecchia e nuova numerazione dei regoli Nestler An instruction booklet, dated 1967, contains the cross reference between old and new numbering system for the Nestler slide rules
