It most certainly is. HK-1300 was stored in "Gus" Conner's junk yard. The A-26 is very likely the former N9424Z which is said to have been stored at MIA for several years. Does anyone know when these planes were scrapped?
The unpainted B-25 is N87Z which was destroyed during a drug run around 1982/ 83. It had previously been flying in a discreet olive drab color scheme with the only identifying mark being a minute N# painted on the tail bumper.
The On-Mark Marketeer was N4050A, most famous for its role in the movie Badlands, which also featured Martin Sheen. It spent some time with Hill Air Co. at FLL before being taken to California where it was combined with another wreck for static display on a USAF base.
