[Tex/LaTex] How adjust hat r from Griffiths David’s book

Question

I have a difficult to center the hat bold accent as in the Griffiths David's book as the picture below extract from the book:

My output using

\usepackage{baskervald}
\usepackage[baskervaldx]{newtxmath}

is different to the original picture of the book.

 \documentclass[12pt,a4paper,oneside]{book}
 \usepackage[lmargin=7cm,rmargin=.7cm,bmargin=2cm,marginparwidth=5.5cm,marginparsep=2em]{geometry}
    \usepackage{lipsum,sidenotes,tabularx}
    \reversemarginpar % Page margins
    \usepackage{graphicx} % Required for including pictures
    \usepackage{xcolor}
    \usepackage{baskervald}
    \usepackage[baskervaldx]{newtxmath}
    \usepackage[scr, scaled=1.1]{rsfso}
    \usepackage{bm}
    \usepackage{amsmath,amssymb}  
    \usepackage[italian]{babel}
    \usepackage[utf8]{inputenc} 
    \usepackage[T1]{fontenc} 
    \usepackage{mathtools}
    \usepackage{dsfont}
    \usepackage{mathrsfs}
    \usepackage{scalerel}

    \def\hrcurs{{\mbox{$\hat \brcurs$}}}
    \begin{document}
    \[V(\mathbf r)=\frac{1}{4\pi \epsilon_0}\int_{\mathcal V} \frac{\mathbf P(\mathbf r')\cdot \hrcurs}{\rcurs^2}d\tau'\]
    \end{document}

In fact my output is:

How should I fix the problem?

Answer 1

\documentclass{article}

%% Preamble
\ifdefined\pdfliteral
    \let\griffPdfliteral\pdfliteral
\else \def\griffPdfliteral#1{\special{pdf: literal #1}} \fi

\newcommand\griffr[1][2]{\leavevmode\hbox{\kern1pt\vbox to1ex{}\griffPdfliteral{%
    q 1 J .27 0 0 .27 0 0 cm #1 w

\newcommand\hatgriffr{\skew3\hat{\griffr}}

%% Body
\begin{document}
    A$\hatgriffr$B\griffr[0.5]C\griffr[3]D
\end{document}

However, the values have to be manually adjusted to scale to surrounding text.
