ID These JBL Cornerhorns ?

I was emailed these pics by Johm who just purchased them and wants to know exactly what they are..

Here is the email I received..

I just bought these and have no idea what they truly are. I know of 1 other pair that surfaced on the web in 2009. There is a rumor that they were made by Bill Hartsfield as a bet between him and William Thomas of jbl. He  said he could build a speaker that uses a 8" driver that would rival the Hartsfield. Only 12 was made according to the rumor. The drivers are d216,075 and N2400. They both have JBL registry cards with consecutive serial numbers for the drivers. The inside horn path looks just like the hartsfield patent drawing. Any info would be greatly appreciated.

Ok JBL experts what exactly does John have here??

Measurements are 32"h x 19" x 19"
