[Proj] Egypt Datum Transformation Parameters

[Irwin Scollar]

Can anyone supply Helmert 7 parameter datum parameters between WGS84 
Ellipsoid and the Helmert 1906 Ellipsoid used in the "Red Belt, Blue 
Belt, Purple Belt, Purple Belt Extended"  Old Egyptian 1907 areas or 
a link to where they may possibly be found?

I have only the 3 parameter Molodensky transform data in the NIMA 
1987 Madtran and the later Geotran2 programs which may not have 
errors as low as those of a modern dual frequency GPS receiver.
