Understood. However, the one for sale is a very very crude facsimile of the one the USAF had in its photo. This must have been a very early prototype from a bidder who didn’t get the job.

Take a look at the one for sale's cockpit and glass and compare it to the cockpit of this TBF Avenger.

I think it's close and it's possible one might have been used to construct the one for sale.
