Mr B,
Roger Brooks (I hope I've remembered his name correctly) a former Victor crew chief has written a book on the Victor which is being published by Crecy.
Dan W,
I have a way better anorak than you.
Though Harbin made the H-5 (the licenced Il-28) it produced only a handful of H-6s from kits supplied by Tupolev, before the big split between the filthy reds and the inscrutable reds.
Thereafter (and after the usual dislocation and politicking of the Cultural revolution) all Chinese 'Badger' production (as opposed to final assembly) has been by Xian.
ALL of the H-6 tankers (there are two distinct variants, one used by the PLA Air Force, one by the Navy) are Xian-built and Xian designed.
Moreover the H- designation is short for Hong - the Chinese word for bomber, whereas the J- designation indicates a fighter, Q- an attack aircraft and JJ- a fighter trainer. Confusingly, export aircraft have anglicised designations - thus H-6s are known as B-6s, and export J-6s and J-7s are F-6s and F-7s, while the Nanchang Q-5 Fantan becomes the A-5.
