Help With A Swiss Puzzler?

I haven't been able to figure the exact place of cancel of this Swiss stamp. Can you help?
Apparently the top of the cancel puts it from Lugano. I think.
It's the bottom inscription in the cancel -- "Fattorini" -- that I can't place.
I've found a trucking company and individuals with the name Fattorini, but no places. Is it a district/neighborhood of Lugano? A street? The name of a particular post office or building? A community outside of Lugano? Or what?
Thanks in advance for any help anyone can supply.

Fattorini... Could it be on old hotel?

hi, I dont't know.Generally we find under LUGANO; "lettere","stazione"
or "*".Fattorini translated from italian means "Bellboy or groom" !

The Swiss post office seems to use "fattorino" to mean postman.

Here are some citations from an online dictionary (including a few from swisspost.ch):

nigelc: I think so too. In french postman is "Facture".It also means
"bill" Like ;send me the bill...
I am not familiar with Swiss postal practices.In the 19th century France
it was possible too have the stamp cancelled by the postman 'OR" cancel; at your home instead of taking it too the local post office.

Yes, I wonder where the Swiss post office would have applied this stamp and cancelled it given that it's a postage due.

Postman in French is facteur not facture

That's an interesting idea that postmen could have been equipped with postage due stamps and a canceler to use when applying them. Or maybe it was done by postal workers in a post office? But why specify that the postage-dueing was being done by a postal person?
