Today I have finded this document. Was write in 1952 by Squadron Leader Harbison and commentaries of James Jabara.
Is really very interesant and complete, by the side of the MiGs is a little specultative but was the year of 1952 and informations were still very limited.

Interesant to read the problems of operated the Sabres up the 40.000 ft , with the big risk of flame out and the loss of the engine by high pipe temperature. A lot of missions were done very near of this altitude; the MiGs were still more high, by the 50.000ft or more, out of the possibilities of the Sabres. Only way to fight , wait the MiGs went down from the perch.
The document come with the map of the main bases of the MiGs: Antung, Tatung-Kao, Fencheng and Takushan, all PLAAF bases at Manchurie.
The airfields of North Korea(only Uiju and Sinuiju) were used a couple of times: the dirt Rwy of Sinuiju was used as emergency Rwy for refuelling when fuel was not enough to arrive to Antung and at Uiju were deployed a few MiGs, but the experiencie was a very short one. The planes were straffed by the F-86 and two days after all were back at Antung in Manchurie.

Nice document.   Nothing new there, but it's the first time I've seen it all in one place. Well worth the read.
