Thx in advance

Hmm.. Well, its not 'House Brush' ( Sign Painter Collection ), from House Industries.. Sorry..
( But that would be a nice alternate, so to say..
)
It's very similar to House Brush in their Sign Painter Collection. You could also look at the samples in Part 6 of the Script Font ID Guide. I have font samples from Art & Sign and Sign DNA included. They might have this, but I just can't recall all the similar fonts.
The font Gee Whiz, made falsely italic and with kerning left as is, yields this:
Gee Whiz hails from Dinc Type who I don't believe ever offered an actual clone
of a commercial font, but many of their offerings over the years were clearly
manipulations of existing commercial fonts � often with lowercase only and
poorly done.
In any case, the font used appears to have been Gee Whiz and who knows what
it started out its life as (my vote would be for Dom Casual Italic, modified and
using the N to make the M).
Hmm ... I didn't link like I usually do, not knowing how Dinc, with
fonts of dubious parentage, would be taken. Now that I search,
I can't find Gee Whiz anywhere any more either.
Since the ReadMe for Gee Whiz states that it may be shared and
that it is "free for all personal, business and commercial needs",
I'll send it your way, Christophe. I hope that you don't need anything
beyond A through Z and basic punctuation.
Here's a link for Gee Whiz, Mike F, for future reference. Even though I've said it before (in the MyFonts forum), I'll say it again here: your generosity in sharing your knowledge is extraordinary and greatly appreciated.
