Actual airframe timeline - Courtesy of

Marketeer - Early, circa 1959 - ( 44-34755 ) ownership was transferred from Flint Steel Corp, Tulsa, OK to Mid America Pipeline Co, Tulsa, OK in 1966, registered as N256H.
 
Marksman #6 ( 41-39221 ) ownership was transferred from Southern Natural Gas Co, Birmingham, AL to Mapco Inc ( read = Mid America Pipeline Co ), Tulsa, OK in 1966, registered as N3035S.
In June 1968, Mapco Inc ( See Mid America Pipeline Co ), swapped registrations between their two On Marks, the Marksman becoming N256H, and the Marketeer becoming N3035S.
 
Marketeer - ( 44-34755 ) ownership was transferred from Mapco Inc ( See Mid America Pipeline Co ), Tulsa, OK to John Rourke, Bartlesville, OK in 1969, registered as N3035S.
 
Marksman #6 ( 41-39221 ) ownership was transferred from Mapco Inc ( read = Mid America Pipeline Co ), Tulsa, OK to Bancroft Manufacturing Co, McComb, MS in 1970, registered as N256H.

 
 
 
 
Richard continues, Probing around with the magic window I found this statement :
 
PR Newswire ; November 21, 1995;700+ words
...America Pipeline Company is a subsidiary of MAPCO NATURAL GAS LIQUIDS Inc., a business unit of MAPCO Inc.(NYSE: MDA). MAPCO NATURAL GAS LIQUIDS Inc. is one ...
 
MAPCO Natural Gas Liquids Inc.  

Address:

PO Box 645, Tulsa, OK 74101, United States

 

Conclusion:

With this, I feel that  Mid America Pipeline Co ( MAPCO ) purchased both an On Mark Marketeer - ( 44-34755 ) registered N256H,

n256hx3.jpg

And a Marksman ( #6 ) - ( 41-39221 ) registered N3035S,

Sometime in 1966, with the Marketeer being acquired first.

In June of 1968, probably deciding to operate only one of the two aircraft, decided to retain the Marksman, but with the Company recognizable registration number  " N256H " . The registration was exchanged between the two aircraft, and the Marketeer, now registered as N3035S was put up for sale.

The Marketeer - ( 44-34755 ) ownership was transferred from Mid America Pipeline Co ( MAPCO Inc. ), Tulsa, OK to John Rourke, Bartlesville, OK in 1969, registered as N3035S.

The Marksman ( #6 ) - ( 41-39221 ) ownership was transferred from Mid America Pipeline Co ( MAPCO Inc. ), Tulsa, OK to Bancroft Manufacturing Co, McComb, MS in 1970, registered as N256H.

The timeline, accompanying photos, and corporate structure I came up with, supports this hypothesis.
