Invincible D-D Monoplane - Manitowoc WI

So, I'm looking for anyone that has additional information on the original 1929 Invincible D-D Monoplane Models 200 and 400.
The reason is actually pretty cool.....I have the original prints ( not replicas ...the machine and paper prints with notes )....but I'm missing the logs and some history on them.
I've done internet searches, but unfortunately, most of the contacts have past away and the stories seem a little contradictive.

Reach out to me if you any additional information.

Awesome find! Hope you can share the Model 200 plan with us too, so we can clearly see the differences.


The Aircraft Division of the Invincible Metal Furniture Co. was founded in 1928 in Manitowoc, Wisc., with John A. Schuette as president.
A total of five aircraft were built before aircraft production was put to a stop because of the Depression:

• c/n 101 — Center-Wing [X337E], a three-/four-seat cabin monoplane with semi-cantilever wing designed by Irl Beach. It was powered by a 110 hp LeBlond 7DF engine.
• c/n 102 — Model D-D [X631], a version of the previous prototype with the more powerful 185 hp Curtiss Challenger engine.
• c/n 103 — Model 200 [C55N], a two-seat monoplane with full cantilever wing, also designed by Irl Beach. It was powered by a 100/110 hp Kinner B-5 engine.
• c/n 104 — Model 400 [C370V], a second example of the Center-Wing prototype with a different designation.
• c/n 105? — A seemingly undesignated mid-wing racer prototype with open cockpit and wheel spats. Engine unknown. Not registered.

I'm attaching the entire Vintage Airplane article on Invincible from October 1973 issue.

Very cool. Are you willing to share the prints or sell them? I would pay to have them copied.

Indeed an awesome find.

Hard to find information on the Invincible, there was a small article in Airwars No19 fall 1989 not specific mentioning the types.

I know there was a wing still sitting in the basement of Invincible in Manitowoc as of 10 years ago. It may still be there
