What ever happened to the Corsair from Cupples in ST. Louis

[Mark Cook]

For years there was a partial airframe at a factory in St. Louis MO.
I think they used it to test panels that they manufactured.
The company ended up going out of business, and the Corsair disappeared.
Anybody know anything about it?
The company was called Cupples products, and was located at the corner of Manchester and Hanley Roads.
Thanks,
Mark
