Bill300d, I just checked my list of tools for my tool boards and the Mossberg 608 is the same, has the long prongs.
my Walden VG2 has short prongs, same style long handle. I have the Walden VG3 short stubby handle, also short prongs.
my tools are not mounted yet. both boards are original Walden & a Mossberg one is 1917 and the other is 1923 and
both were for Ford Model-T tools. both boards had been stripped of the hooks and left roughed out holes.
I hope to find every tool to fill them before I leave this life.
