Mocking up top irons..
What..or how does the windshield post
Secure the top...
It seems the top iron is a "form" that
Creates a leading edge ahead of windscreen.
Is there... a wood piece embedded in the top
that pins or hold the top secure against the wind effects?
Is this all included in a classique top kit?

The top structure is made of 'irons' and 'bows'.
The top structure is then 'padded' and 'strapped' to the body to hold the structure.
The front bow has a pair (L, R) of 'clamps' that bolt to the face of the front bow, and a wing nut locks it to the windshield post.
The clamps are bolted to the 'inside' face of the front bow. The top covering kit from the makers is only the padding, straps, and rear curtain, and top cover, included normally with a 'wind/rain' flap piece that is wrapped/tacked around the front bow and hangs down in front of the upper windshield frame to keep out wind.
"Top Kits" don't have irons, wood bows, or brackets.
The model years for this style top are 1923 - 1925.
The Classtique kit will not include irons/sockets or bows.
It will include the bow wraps, wind flap, top tension straps, top pads, rear curtain with the rear window configuration of the model year of your car, and the top material. It will also include a roll of "hide-em" welt and the metal trim tips for the welt. The tips that come with the kit will be later reproductions and do not exactly match the original tips.
