Post 317 from Stitcher. 1st photo was probably taken only 2 to 3 years ago. Aircraft to the right is an Antonov 12 Russian built freighter. So 2014 or 2015.
2nd photo a little more recent. Note the demolition of what was the old International departure and arrival building, still there on 1st photo,this was demolished in the last couple of years so probably 2015 or 2016.
3rd and 4th photo around the same time period 2015 or 2016.
Post 320 from Stitcher , I would say pre war 1939. Note Hangers 2 and 3 not yet built.
The aircraft is a Percival Q6, The private executive aircraft of that time. Not many built.
OldMohawk Post 325. 1st photo was taken at the airport open day on 2nd April 1960. Blackburn Beverly aircraft to the extreme right. The day was to celebrate the return of the airport back to Birmingham City council control.
2nd photo Miles Marathon, non now in existence. Derby Aviation later to become British Midland was the largest civilian operator of the type.
Last photo looking at the early Aer Lingus scheme probably 1949 or early 1950s. See the later scheme in post 316 from Stitcher.
Hope this info is of some interest.
Great photos, particularly the early ones. Keep them coming Stitcher and OldMohawk.
