I must say I am flattered that there is still interest in the Typhoon File, published in 1981, if somewhat appalled by the prices asked!. However it does have its shortcomings as much further information has come to light in the intervening years. A brief history of ‘histories’ might be helpful.
The original Typhoon File was compiled using the Air-Britain technique established by Jim Halley and used for his Serial Registers and type histories in Aeromilitaria. The basis for each history was of course the Form 78 with details of fates added from the Form 1180s (accident cards) and the unit ORBs. This left a lot of unexplained gaps (filled on the Form 78s by ‘P(presumed)SOC 21.6.47’ - a paper exercise which wrote off anything that did not appear on a post-war census).
I was soon working on what would become the ‘Typhoon and Tempest Story’ (1988) with Chris Shores and realising there would not be room for a full list of histories (publisher’s decision) decided to list all the accidental and operational losses. I was aided in this by limited access to casualty records and the discovery of some OR101s - a regular return from 2ndTAF squadrons stating aircraft received and lost - unfortunately incomplete and only used in the latter half of 1944. Jim Halley used the Typhoon and Tempest Story loss list when he revised the serial registers in the 1990’s.
Enter Mr Bickers with his ‘Typhoon, the Combat History’. Mmm. The individual aircraft ‘histories’ without doubt have been lifted verbatim from the updated Air-Britain serial registers, with the omission of aircraft which (apparently) did not have use by a flying unit. Without acknowledgement or, as far as I know, permission.
The ‘histories’ in the F.K.Mason Typhoon/Tempest book have so many omissions and inaccuracies they can be disregarded.
Next came the 2ndTAF series which brought even more updates. Constant cross-referencing of records made me realise the scale of errors on the Form 78s and in the ORB. In the former, entries were quite often made on the wrong card - on the adjacent card, or one with a similar serial eg. JP and JR MN and MM, even R8 and RB. I have my own cards which track all the changes and include information from all sources, such as RAE and A&AEE cards, ATA deliveries, pilots logs, spotters logs (good ol’ Ray Strurtivant) etc.
I have started a list of consolidated updates to the original Typhoon File - but am so far only up to JP495 and the fourth Wingleader book has priority. When complete I’ll make it available but I’m not sure how at present.
