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

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 my grandmother’s brother!
Nestler Cross Reference

An instruction booklet, dated 1967, contains the cross reference between old and new numbering system for the Nestler slide rules
