HA-300 Docs

[Airliner]

Does anyone have any docs referring to Hispano Aviación/Helwan HA-300 like operations or maintenance manual for it ? Would really appreciate if anybody has anything here.

Hi I do remember a very indepth article written by an old acquaintance of mine, Pushpindar Singh on the HF-24 Marut, which mentions about the H300 engine, the powerplant of the Helwan H300, being tested in a Marut airframe which had been specially adapted by HAL. The modifications allowed for either engine bay to take the original Orpheus or the H300. It mentions that the first flight of the H300 powerplant was in a configuration of one H300 and one Orpheus in the HF-24. Not sure if this info helps!
