# Better way to produce V\llap{--}

Is there a better way to get the symbol produced by V\llap{--}? I need it in math mode. The symbol is someitmes used to represent volume. The above hack is not the right symbol but something close.

How about \forall? Does it fit your requirements? –  Count Zero Aug 27 '12 at 12:29
@CountZero I need the dash to extend beyond the V. –  mythealias Aug 27 '12 at 12:37
Can you please upload (provide a link to) an image showing the desired symbol used in context? –  Gonzalo Medina Aug 27 '12 at 13:05
@GonzaloMedina the symbol is usually used when writing Reynolds transport equation. This pdf file shows it in use. –  mythealias Aug 27 '12 at 17:36
\documentclass{article}
\newcommand{\volume}{\mathop{\ooalign{\hfil$V$\hfil\cr\kern0.08em--\hfil\cr}}\nolimits}
$\volume(abc)$
