"Aircraft Production" magazine apr/may 1942

While going through some of the stuff from the previous owner of our Spitfire project, I came across photocopied pages from a Magazine called Aircraft Production. These photocopies were from two issues one in April and one in May 1942. The Articles where titled The Spitfire in Production. After going through these copies would like to try and find original copies of this magazine or even a reprint edition. If anybody has any knowledge of copies of this magazine being for sale please contact me.
