#8 & 9: C-82 similarity is, I suggest, conceptual. By the date of the Application, 5/53, C-119 was the product for which UK made an MSP bid. Any Sister Firm work and/or licence by Blackburn would have been on that. But I doubt any such thought entered the mind of Blackburn's Board. They had bought General despite, and not because of (to be) Beverley.
36 of the 42 Blackburn B.2 trainers had been operated to 1942 by the contractor for No.4 E(R)FTS/Brough...Blackburn A/C Ltd, who also owned (wef 1938) the contractor for No.5 E(R)FTS/Hanworth, the London Flying Syndicate, who in 1944 bought the freehold of Feltham Air Park/Hanworth Aerodrome, thus becoming landlord of General A/C. Hanworth was blighted for flying as Heathrow grew; General ran out of work when assault gliders succumbed to Pioneers and choppers. Blackburn did not buy them 1/1/49 for the son-of-Hamilcar scheme that became Beverley, but to close down the activity that was diminishing the value of the site....which Blackburn sold well to the Local Authority in 1956.
Blackburn has a treasured place in anybody's list of the World's Worst A/c and faced dereliction 3/51 when Y.B.1/B-88 lost to Fairey Gannet. (How odd that they diversified into aftermarket support of the Jowett Javelin car!) 30 BPA Balliols, then Vampire wings and 20 Beverlies kept them alive, increased to 47 after they schemed best for (to be) Buccaneer. RAF would have been entirely happy to support brown jobs with the same C-119G as many others, and were embarrassed to take delivery of blunderbuses after others had C-130A/B.
