Help please! I'm looking for this font.
If anyone can help I will be grateful.

Amsi Narrow Bold  Sugerida por donshottype 

AFAIK this logo, which appears as compass patch that buttons onto the upper sleeve of the left arm of apparel from Carlo Rivetti's Sportswear Company, is not a font.

EDITED:
Closest font to the letters in the logo is perhaps Amsi Pro Narrow Bold -- NOT THE FONT -- which has a similar relaxed _S_ and the rounded tips.

@donshottype I know that the whole thing is not a font. I only meant the letters not the whole logo.
I think it's that font what you have suggested.
Thanks for your help!
