Oh no!  It's the TV Tray* style.  That may take a bit of fiddling, as there
are some big differences in the tops of some, tho it may not matter much.

Like all workmates, there are differences in the years.  Mine is fairly new
2008, and looks different from the one shown in the picture, and is not
double thick at the jaw..  Someone else will need to chime in with the
sizes, but further below are some notes.

Mine is only 24" wide, vs the 29" of the big ones, and ~4 vs 5" deep.
The Biggest other difference, which may matter, is the mounting on mine is
different from the one shown, I have 2 through holes instead of being
mounted from below.  I will add a pic at the tail end to show how mine
mounts.
