Need to decipher markings

[TCLARK]

I am half way thru my restoration of
a C15A Cab 12 from the southern Alberta area.
I am about to start the body work and took pics of
some markings as I will probably add those back on as
close as possible when I repaint.
The right front fender has a 7 in diameter
cowboy on a bucking bronc is this familiar or
a possible later add on??
The left front fender has a 7X7 in hand painted orange square
with (I believe) " 10" on it.

Both doors have markings as shown in the last photo and
these are the ones I really want to know about!

Any help would muchly be appreciated as I want
return this truck to as close as original.
Thanks again Terry
