The one on the left is a high cowl used on 24-25s and TTs for 26-27. The one on the right is a low cowl--Pre 24 (when not wood).

Or High hood vs. Low hood as many refer to them. :-)

One on the left only has the magneto coil box hole, no battery post?

Magneto or battery was selected by the Ignition switch.

The magneto post became the "coil" post when the ignition switch on the dash took over the duties of switching between battery and Mag. There was no need for two posts. Both sources are routed to the switch and the position of the switch determines which source is fed to the coils.

Forgot to mention - The hole in the firewall is still there. The coil box dropped the extra post.

I've seen at least four different styles of high firewalls. The differences are trivial, but they are there.

Larry,Did the 25 firewall still have the holes where the priming bell crank went?

They did. Also the '25 firewall has 3 holes for the felt. The 1924's had 5.

Also the high firewalls had a riveted bracket to hold the bonnet stay rod. The later ones it was pressed out of the metal and stamped in one piece. Over here the riveted design is the 1923-24 models with the 1925 the one piece stamped design.
