A blueprint is a drawn document that details the construction of or assembly of a item, project or device. It calls out specifics of what is shown in the drawing and gives their location and dimension or provides notations as to their composition or assembly.

A blueprint is a reproduction of a technical drawing or engineering drawing using a contact print process on light-sensitive sheets. Introduced by Sir John Herschel in 1842, the process allowed rapid and accurate production of an unlimited number of copies. It was widely used for over a century for the reproduction of specification drawings used in construction and industry. [...] The process was not able to reproduce color or shades of grey.
The process is now obsolete. [...] The term blueprint continues to be used less formally to refer to any floor plan (and even less formally, any type of plan).

Disegni tecnici con finiture Following Claudia's suggestion to search on Google Images, here is an image explaining what they are: https://picclick.it/FIAT-TOPOLINO-500C-DISEGNO-TECNICO-CON-F...

The caption reads: "DISEGNO TECNICO CON FINITURE e NUMERI COLORI"

One hit for this phrase refers to a scale of 1:20, implying that they're drawings.

I don't have much more material than this at the moment, sorry. I cannot tell whether it's a typo/mistake, but it looks like it's not the only occurrence on Google... It could refer to the manuals you linked to (though it would kind of repeat the previous item in the list), let's see if others can confirm it. Thanks!

Désolée,j'ai été trop rapide. Il s'agit bien d'un 'manuale complessivo' cf. https://www.ricambi-triumph.it/triumph-motocicli/prezzo/4345...

Avez- vous le texte original ? Ne s'agirait- il pas d'une erreur reprise par plusieurs (cf. Amazon,etc.) ?
